Did the glaciers make that?
Just</b> <b>remember that's a pile of</b> <b>slag under there, an old</b> <b>industrial waste.</b> <b>Forms our infrastructure here.</b> <b>We always take a look at the lake</b> <b>and assume the lake</b> <b>has always been that way.</b> <b>But you know, if you go back</b> <b>before the start of the Pleistocene,</b> <b>before the start of the Ice Age.</b> <b>(upbeat music)</b> <b>There's no lake there.</b> <b>It's a huge river valley,</b> <b>the Erigan River Valley.</b> <b>When you fast forward to</b> <b>the start of the Pleistocene,</b> <b>two big lobes of the glaciers came out</b> <b>and they were scouring</b> <b>out the Lake Erie Basin.</b> <b>Just think about glaciers as bulldozers</b> <b>when they're moving forward.</b> <b>They're pushing stuff</b> <b>forward, stuff is embedded,</b> <b>and then when they retreat, they don't</b> <b>kind of pull up their trou.
They melt.</b> <b>And so whatever they're carrying in the ice</b> <b>then settles down and so you had</b> <b>a ridge that was established.</b> <b>And then when they finally stalled the</b> <b>last time at the end of</b> <b>the Wisconsin glaciation...</b> <b>Imagine that they're covering pretty much</b> <b>the entire Lake Erie Basin.</b> <b>And that starts the first of a series of</b> <b>the ancestors of Lake Erie.</b> <b>First, a glacial lake, Maumee.</b> <b>And then, as the glacier starts melting</b> <b>back in these two lobes,</b> <b>it stalls at one point, literally where</b> <b>the edge of the glacier is right between</b> <b>Long Point and Presque Isle.</b> <b>It's just to the north of Erie.</b> <b>Then, fast forward, finally this glacier</b> <b>is poking its way,</b> <b>melting all the way back.</b> <b>And sometime around 12,000, 11,500 years</b> <b>ago, the Niagara outlet opens up.</b> <b>One of the things to celebrate about Erie</b> <b>is you have Presque Isle.</b> <b>You have so many habitats, so much</b> <b>diversity of habitat,</b> <b>and then all of the plants and animals</b> <b>associated with them in such a small</b> <b>amount of real estate.</b> <b>It's part of this biological powerhouse,</b> <b>but it's kind of like you get all of the</b> <b>western basin confined in a small little</b> <b>area right off of downtown.</b> <b>It's a pretty neat thing.
I'm envious.</b> <b>[sound of VCR rewinding]</b> <b>Presque Isle is this 3,200-acre peninsula.</b> <b>We have so many different ecosystems on</b> <b>the peninsula, from the water's edge all</b> <b>the way to the climax forest.</b> <b>And so it supports a</b> <b>lot of different wildlife.</b> <b>And it is constantly changing.</b> <b>[music]</b> <b>You know, I heard the expression used,</b> <b>and I love it, that Lake</b> <b>Erie is like a hummingbird sea.</b> <b>It's got this really fast metabolic rate.</b> <b>[music]</b> <b>Because it's shallow, the furthest south</b> <b>of the Great Lakes, and all of the</b> <b>organic material coming in,</b> <b>not only from the Detroit River, but</b> <b>especially the Maumee River, all of these</b> <b>nutrients coming in, it</b> <b>is a biological powerhouse.</b> <b>And by far and away, it produces more</b> <b>biomass than all of the rest of the Great</b> <b>Lakes, I believe, put together.</b> <b>All of that said, however, it's also</b> <b>exquisitely sensitive to too much</b> <b>nutrients coming into the water.</b> <b>And being shallow, if you get too much</b> <b>algal activity, and then that algae at</b> <b>the surface dies off,</b> <b>and then the things that decompose it use</b> <b>up the subsurface oxygen, you can get</b> <b>dead zones in the lake.</b> <b>And, you know, we know, famously in 1969,</b> <b>when they proclaimed</b> <b>Lake Erie as being dead,</b> <b>it wasn't dead, it just had dead zones in</b> <b>the middle of winter</b> <b>that had become anoxic.</b> <b>While the conferences and committees</b> <b>continue, the dying</b> <b>flow to Lake Erie goes on.</b> <b>And that oxygen is a really important</b> <b>thing, and they wouldn't get any kind of</b> <b>restoration until the fall,</b> <b>when surface waters and subsurface waters</b> <b>reach the same temperature, then you get</b> <b>this turnover of the water,</b> <b>and you have oxygen-rich waters coming</b> <b>down to the bottom, and those bottom</b> <b>waters coming up to the top that help</b> <b>recharge the system.</b> <b>I've wanted to be a weatherman since I</b> <b>was eight years old, so I guess that's 53</b> <b>years that I've actually enjoyed weather.</b> <b>[Music]</b> <b>If you look at any part of the country,</b> <b>any part of the world, you know, every</b> <b>place has their own</b> <b>little idiosyncrasies,</b> <b>or what we call microclimates.
As the</b> <b>name implies, these are climates on the</b> <b>scale of, you know,</b> <b>maybe a few tens of miles.</b> <b>And Erie is no different.
Erie is unique</b> <b>than most because we also have a pretty</b> <b>good rise in elevation from the lake to</b> <b>even I-90 and beyond.</b> <b>So the lake affects our weather in two</b> <b>major ways.
It affects the temperature,</b> <b>and it affects the humidity.</b> <b>In the summertime, the lake tends to have</b> <b>a cooling effect because the lake is</b> <b>typically, during the</b> <b>day, cooler than the land,</b> <b>so it gives a cooling effect, at least</b> <b>along the lake shore.</b> <b>But really, when we think of lake effect,</b> <b>we think of those heavier snow squalls</b> <b>that are in effect</b> <b>because the lake adds heat,</b> <b>which adds instability, it adds moisture,</b> <b>which not only adds moisture for the</b> <b>clouds and snow to form,</b> <b>but adding moisture also makes the air</b> <b>unstable, allowing the clouds to rise to</b> <b>higher heights and</b> <b>allowing more snow to fall.</b> <b>Officially from a weather service</b> <b>standpoint, most, the weather service</b> <b>divides their</b> <b>forecasting areas into zones.</b> <b>In the vast majority of those cases,</b> <b>they're on a county level.
So Crawford</b> <b>County is a zone,</b> <b>Warren County is a zone.</b> <b>Erie County and many of the zones right</b> <b>along the Great Lakes, at least, in the</b> <b>Chautauqua County, Erie</b> <b>County, PA, and Ashtabula County,</b> <b>there's two zones, basically north of 90</b> <b>and south of 90.
So there are several</b> <b>zones, and across the country,</b> <b>there are zones where, you know, the</b> <b>microclimate of the lake shore, actually</b> <b>the weather service recognizes that as a</b> <b>separate zone with its</b> <b>own separate forecast.</b> <b>Presque Isle is constantly changing,</b> <b>and so a lot of that has to do with it</b> <b>being right on the front of Lake Erie,</b> <b>subjected to wind and water and waves and</b> <b>erosion, and that</b> <b>changes the shape of it.</b> <b>But we also try to maintain, you know,</b> <b>the existing shape of it because it is an</b> <b>important part of our tourism, of our</b> <b>economy, of, you know, the people that</b> <b>live here, our community.</b> <b>[Music]</b> <b>Hurry, hurry, hurry to the glorious</b> <b>beaches of Presque Isle!</b> <b>If she had her way, Presque Isle would be an</b> <b>island.
But like my second wife, much to</b> <b>her chagrin, we couldn't let her leave.</b> <b>And how could we let her go?
If not for</b> <b>her and the protected bay, it would be</b> <b>just another lakefront, crime-infested</b> <b>backwater village like</b> <b>Cleveland or Buffalo.</b> <b>Gross!</b> <b>Since the turn of the century, our</b> <b>nation's best and brightest minds, the</b> <b>Army Corps of Engineers, has prevented</b> <b>the separation of the Isle from the</b> <b>mainland, creating barriers to keep the</b> <b>sand from wandering,</b> <b>unlike my first wife, Jo-ann.</b> <b>I even named my Paasch turtleback after</b> <b>her, and she still left me for some jokester</b> <b>in Detroit with the Sugarhouse guy.</b> <b>But I digress.
To get back</b> <b>to the baaaayyy-sics.
Ha ha!
Funny!</b> <b>This humble natural oasis offers a quaint</b> <b>little lighthouse ready to move in.</b> <b>Pay no mind to the previous Lighthouse</b> <b>Keeper's review.
It is not, in fact, the</b> <b>loneliest place on Earth.</b> <b>That title's reserved for the Stannard</b> <b>Rock Light in Marquette, Michigan.
And</b> <b>who likes Michigan anyways?</b> <b>As bitter as Keeper Waldo may be, he and</b> <b>his wife Mary still managed to have a</b> <b>beautiful baby girl, the first babe born</b> <b>right on the peninsula.</b> <b>Yeah, not all that lonely after all, huh?</b> <b>Oh, Presque Isle... this lovely sand spit is</b> <b>just across the bay from the hustling</b> <b>bustle of Erie, P.A., the vacation</b> <b>destination of your dreams.</b> <b>Catch a pleasure steamer from the Public</b> <b>Docks to the luxurious Massassauga Hotel,</b> <b>right at the Head of the peninsula, a hoppin'</b> <b>place to see and be seen</b> <b>in various states of undress.</b> <b>You might even see a flirty calf or two</b> <b>during the Sassafras 2-step.</b> <b>[whistles]</b> <b>And if dancing doesn't tickle your fancy,</b> <b>high-rollers can pop upstairs for a</b> <b>high-stakes game of 5-card stud.</b> <b>[record scratch]</b> <b>[music]</b> <b>What's that?</b> <b>[whispers]</b> <b>Ya don't say.</b> <b>I'm sorry folks, the party</b> <b>must have gotten too hot.</b> <b>That's lit.</b> <b>The Massassauga Hotel burned down in 1882.</b> <b>You might have better luck checking out</b> <b>the picnic grounds at</b> <b>the forest by the sea.</b> <b>Waldameer.</b> <b>There's a newfangled trolley that'll take</b> <b>you right there from downtown.</b> <b>And if you do decide to put on your</b> <b>bathing costume and take a dip,</b> <b>don't you fret about riptides.</b> <b>The brave boys at the Lifesaving Service</b> <b>will scoop you up and dry you out like</b> <b>that nuisance sturgeon on the pier.</b> <b>They've got ample practice because</b> <b>they've been doing it since 1876.</b> <b>But boy oh boy, don't think the</b> <b>excitement ends here folks.</b> <b>Big things are afoot.</b> <b>Gossip on the party line is they've made</b> <b>this isthmus you want for</b> <b>Christmas into a whole state park.</b> <b>There's even talk of a paved road.</b> <b>No more trudging through the</b> <b>mucky marsh for you fancy folk.</b> <b>We'll leave the wetland</b> <b>wallowing into the likes of Joe Root.</b> <b>Of course I'd be amiss if I didn't bend</b> <b>the knee and kiss the</b> <b>grits of one Isador Sobel.</b> <b>Like Peter the Hermit, he let the folks</b> <b>of Erie upon a crusade to raise the funds</b> <b>and raise the proverbial</b> <b>roof of our prettiest park.</b> <b>And by golly he did it.</b> <b>And more!</b> <b>Sobel got together five thousand bucks</b> <b>more than what was needed.</b> <b>But we all had cash to spare in the</b> <b>golden days of the roaring twenties.</b> <b>And you'd be a rube if you didn't take</b> <b>this chance to catch all the flora and fauna</b> <b>frolickin' from hither and yon.</b> <b>P.I., as the locals call it, isn't just</b> <b>for the sapiens but also for the birds.</b> <b>This park is a terrestrial and</b> <b>extraterrestrial landmark.</b> <b>Even the feds know it.</b> <b>We're just so good at conservation that</b> <b>the National Park Service just had to</b> <b>recognize us as a natural landmark.</b> <b>Not just that, but even beings from other</b> <b>planets reportedly paid us a visit.</b> <b>With more bird watchers than you could</b> <b>shake a stick at, we're surprised none of</b> <b>them identified this flying object.</b> <b>Now don't worry Patty, it was probably</b> <b>just a Wilson's snipe.</b> <b>Don't wait for the ferry!
Get ready for a</b> <b>trip around scenic Presque Isle!</b> <b>Now with two whole lanes for you and</b> <b>everyone else you can</b> <b>pile into the station wagon.</b> <b>Pro tip, my third wife and I love taking</b> <b>a saunter down at Misery Bay.</b> <b>It's better than Stinkhole.</b> <b>Don't forget your Coppertone and</b> <b>Polaroids; preserve that sunset in your</b> <b>scrapbook, not on your skin.</b> <b>It's all waiting for you at</b> <b>the world famous Presque Isle!</b> <b>It won't be here</b> <b>forever, just like Joanne.</b> <b>I was almost born on Presque Isle Bay.</b> <b>My mom was out fishing</b> <b>the night before I was born.</b> <b>(soft music)</b> <b>Cascade Creek was within</b> <b>walking distance in my house</b> <b>when I was young.</b> <b>And my parents told me,</b> <b>you know, don't go there</b> <b>because you could get sick, you know.</b> <b>There was human sewage</b> <b>floating down that creek.</b> <b>There was oil, there was suds,</b> <b>there were different colored dyes</b> <b>and heavens knows what else was there.</b> <b>A friend of my dad's,</b> <b>Clyde Williamson, said,</b> <b>"Well, when I go to college,</b> <b>I'll study and clean up Cascade Creek.
"</b> <b>Because he said that</b> <b>100 years before that,</b> <b>he said it was one of the best trout</b> <b>streams in the area.</b> <b>And of course there</b> <b>were no trout there then.</b> <b>As far as the lake itself,</b> <b>it was really bad in</b> <b>the late 50s, early 60s.</b> <b>Presque Isle Bay used to have Cladophora,</b> <b>which is a type of filamentous algae</b> <b>and it would wash up on the shore and</b> <b>just big mats of it.</b> <b>I mean, it'd be all over the shoreline.</b> <b>And it was so thick on the</b> <b>top of the water at times</b> <b>that the turtles could</b> <b>climb up on top of the stuff</b> <b>and be half the shell out of the water</b> <b>just with the Cladophora.</b> <b>When I started with the state,</b> <b>back in 1966 or thereabouts,</b> <b>the Pennsylvania Clean</b> <b>Streams law just went into effect.</b> <b>So here's a kid in his young 20s</b> <b>going around telling people,</b> <b>"You can't dump that</b> <b>in the water anymore.
"</b> <b>I was not a real popular person.</b> <b>It was different.</b> <b>I had my life</b> <b>threatened a couple of times.</b> <b>I guess part of the</b> <b>thing that I had pride in</b> <b>that I grew up there</b> <b>and I could see changes a</b> <b>little bit at a time, you know?</b> <b>And it wasn't just my job</b> <b>as a God-fearing person.</b> <b>I wanted to do the right</b> <b>thing for the environment</b> <b>and for, try to do the</b> <b>best I could for the public.</b> <b>- Keeping our waters free from pollution</b> <b>and conserving our</b> <b>underground water supply</b> <b>is of direct and</b> <b>immediate concern to us all.</b> <b>For ultimate success,</b> <b>the campaign must have the</b> <b>full and continued support</b> <b>of the people of this great state,</b> <b>a people aware of and</b> <b>willing to pay the cost</b> <b>of vital anti-pollution measures.</b> <b>Only then can we fully realize our goal</b> <b>to bring to all of us at</b> <b>home, at work, at play,</b> <b>once again, pure and clean,</b> <b>the waters of the Commonwealth.</b> <b>- We got two problems.</b> <b>You got the biotic and the abiotic.</b> <b>The abiotic is like the chemicals</b> <b>and the biotic would be the invasives.</b> <b>And even without the invasives,</b> <b>you still have the balancing act</b> <b>of how many fish can you</b> <b>catch in nets or hook and line</b> <b>or natural causes or disease, you know.</b> <b>So everything's playing together.</b> <b>The blue pike, oh, it was</b> <b>a big industry, yeah, yeah.</b> <b>There were a lot of boats going out there</b> <b>and there was a lot of competition too.</b> <b>I had talked to one of</b> <b>the commercial fishermen</b> <b>and he indicated there'd be so many gill nets.</b> <b>When you pulled yours</b> <b>up, if it was at the bottom,</b> <b>you're pulling up</b> <b>somebody else's gill nets</b> <b>and there were miles and</b> <b>miles of gill nets out there</b> <b>for the blue pike and didn't really think</b> <b>that there were a problem at first</b> <b>and they disappeared basically.</b> <b>- Things that were going on</b> <b>100 years ago or 20 years,</b> <b>we didn't know any better.</b> <b>We were stupid.</b> <b>We were only concerned about</b> <b>getting your business going</b> <b>and we did all kinds of crazy</b> <b>things with the Great Lakes.</b> <b>When I went to college in 1960,</b> <b>there was no such thing as</b> <b>environmental science courses.</b> <b>You could be a doctor,</b> <b>lawyer, an Indian chief,</b> <b>but there was nothing</b> <b>to do with concentrations</b> <b>in the environmental theory.</b> <b>So it's all changed.</b> <b>These are all "new"s.</b> <b>Now blue pike was fished so hard</b> <b>that they eventually vanished.</b> <b>Of course, I was born in</b> <b>1942, so I was still around,</b> <b>but I remember that was</b> <b>pretty much all the restaurants</b> <b>they had blue pike.</b> <b>It was a really good fish.</b> <b>People liked them a</b> <b>lot better than perch.</b> <b>People chose the fish not</b> <b>only 'cause there's the quantity,</b> <b>but they also had the taste.</b> <b>I think the last year that was recorded,</b> <b>they caught it and blue</b> <b>pike was only 100 pounds taken.</b> <b>Afterwards, 22</b> <b>million pounds in one year,</b> <b>way back in the 1920s.</b> <b>- You know, the collapse of any</b> <b>fishery changes the ecosystem,</b> <b>changes the dynamics</b> <b>of all the other fishes</b> <b>and other organisms that live there.</b> <b>And so as you see the</b> <b>rise or fall of populations,</b> <b>you also have to be</b> <b>aware that that has almost</b> <b>like a domino effect on other organisms</b> <b>that live there too,</b> <b>whether it's as a</b> <b>predator or prey species,</b> <b>or depending on if they feed on plankton</b> <b>or if they feed on fish</b> <b>that feed on plankton,</b> <b>it really is a domino effect.</b> <b>In the scientific perspective,</b> <b>we're always learning from</b> <b>what has previously happened</b> <b>and trying to anticipate</b> <b>what might be coming up</b> <b>and how we can monitor</b> <b>and just be on the forefront</b> <b>of things as much as possible.</b> <b>- And years later, when I was working</b> <b>with the Fish Commission,</b> <b>trying to figure out</b> <b>why they disappeared,</b> <b>I sent notices out to different</b> <b>commercial fishermen</b> <b>or retired commercial</b> <b>fishermen in the United States</b> <b>and Canada and the</b> <b>consensus, you know, they had ideas,</b> <b>everything from pollution</b> <b>to the mayflies disappearing</b> <b>and to overfishing and everything,</b> <b>but it seemed that a lot of them thought</b> <b>that the invasion of the exotic smelt</b> <b>had something to do with it.</b> <b>- So an invasive species is a species</b> <b>that is not naturally</b> <b>found in the region,</b> <b>but also causes economic damage.</b> <b>And so you will see</b> <b>that invasive species,</b> <b>you know, are species that</b> <b>do cause some type of damage,</b> <b>but then we also have exotic species.</b> <b>So these might be different plants you</b> <b>buy at the greenhouse</b> <b>and plant in your backyard that are not</b> <b>supposed to be here,</b> <b>but they do not cause an</b> <b>economic impact to the environment.</b> <b>- They introduced a bait</b> <b>fish called the rainbow smelt.</b> <b>Now the rainbow smelt, they thought,</b> <b>well, they've been doing a great thing</b> <b>to give the fish something to eat.</b> <b>Well, they did, they</b> <b>loved them, eat them.</b> <b>Trouble is they couldn't reproduce.</b> <b>They have enzymes in their system</b> <b>that inhibits</b> <b>reproduction and that kind of did it.</b> <b>You couple that with</b> <b>the bad water quality</b> <b>and overfishing and it wiped it out.</b> <b>- It isn't all malicious.</b> <b>People thought that</b> <b>they could improve things.</b> <b>Oh, the Fish Commission people years ago,</b> <b>they thought the carp were wonderful.</b> <b>Well, the carp thought</b> <b>they were wonderful too</b> <b>because there's lots of them around,</b> <b>but it isn't exactly what we want.</b> <b>- We got to worry</b> <b>about the Western portion</b> <b>of our Great Lakes and</b> <b>that's around Chicago</b> <b>with the Asian carp.</b> <b>That's a real problem.</b> <b>And again, it's stupidity of man.</b> <b>They brought these fish, there's a flood,</b> <b>the fish got out and there they are.</b> <b>But it's a good side to it.</b> <b>I understand that they</b> <b>have commercial fishermen</b> <b>are dedicated to catching the Asian carp</b> <b>and are selling it to China</b> <b>because the fish in China are all</b> <b>out of contaminated lakes.</b> <b>And ours are not.</b> <b>They're getting a better price for it.</b> <b>- The problem with</b> <b>invasive species is just that.</b> <b>You don't know the potential.</b> <b>(soft music)</b> <b>So what we know about invasive carp</b> <b>is that the invasive carp</b> <b>spawn in deep flowing water</b> <b>during the summer months.</b> <b>We don't have that here.</b> <b>The Maumee River, the</b> <b>Sandusky River does.</b> <b>More than likely what's</b> <b>going to happen is Lake Erie</b> <b>is going to be where they all come</b> <b>because they'll be able to be born in</b> <b>Michigan and Huron.</b> <b>And they'll just funnel</b> <b>their way down into the system.</b> <b>And we probably won't see</b> <b>much natural reproduction</b> <b>of those fish with the</b> <b>way their morphology is now.</b> <b>But they're going to thrive here.</b> <b>They're going to, this</b> <b>is highly productive.</b> <b>It's where they're going to want to be.</b> <b>And the issue with</b> <b>invasive carp is not the fact</b> <b>that they're going to actively compete</b> <b>with the other species,</b> <b>but there's only so</b> <b>much room for biomass.</b> <b>So as you have more and more big fish,</b> <b>something has to give.</b> <b>- So when we look at</b> <b>the idea of evolution</b> <b>by natural selection,</b> <b>we are looking at that</b> <b>in a natural environment,</b> <b>you might have some change</b> <b>that has happened over time.</b> <b>And within the population</b> <b>of that natural species,</b> <b>they are able to respond.</b> <b>And the generational</b> <b>change or shift is responding</b> <b>to that environmental pressure.</b> <b>However, invasive</b> <b>species is not doing that.</b> <b>You are taking</b> <b>something, creating this pressure</b> <b>in a very short period of time.</b> <b>And that pressure can be very detrimental</b> <b>where it's aggressive.</b> <b>It's eating the eggs,</b> <b>it's competing for space,</b> <b>it's competing for</b> <b>habitat, it's competing for food.</b> <b>- Changes in the lake will take place.</b> <b>We can try to do some</b> <b>things like with the lampreys,</b> <b>you can put out</b> <b>lampricide in the streams</b> <b>and kill off a lot of the sea lampreys.</b> <b>But then there's side effects,</b> <b>you could kill off native lampreys</b> <b>or salamanders and so on.</b> <b>And you still don't</b> <b>kill off all the lampreys</b> <b>so they come back.</b> <b>- You can't do that kind of</b> <b>chemical warfare with fish.</b> <b>We know,we've had</b> <b>it happen in Pymatuning.</b> <b>We had the carp herpes virus come down</b> <b>and it only killed carp.</b> <b>And there was tons and tons of carp</b> <b>that died in</b> <b>Pymatuning just a few years ago.</b> <b>And that got the gears spinning.</b> <b>And one of the things</b> <b>that we constantly point out</b> <b>is you do not want to start messing</b> <b>with chemical warfare on fish</b> <b>because that can</b> <b>never lead to good things.</b> <b>- So I think if we go back to those</b> <b>industrial pollutants</b> <b>and you look at PCBs and DDT,</b> <b>kind of that mindset,</b> <b>if a little does it good,</b> <b>then a lot must be even better.</b> <b>Once it was realized that if you apply</b> <b>a whole bunch more pesticide,</b> <b>you're not getting any further ahead.</b> <b>I think once that was kind of understood</b> <b>that there is a balance,</b> <b>we need to protect what is being released</b> <b>into the air and on the land</b> <b>because that also impacts the water.</b> <b>That also eventually impacts us.</b> <b>And so regulations were put in place</b> <b>to control how much of these contaminants</b> <b>were allowed to be used or</b> <b>released in the environment.</b> <b>- So I guess what I'd like to do</b> <b>is make sure that</b> <b>people start paying attention</b> <b>to the chemicals</b> <b>they're putting into the lake.</b> <b>And I don't know, did I say,</b> <b>if I could just leave a</b> <b>message for future generations,</b> <b>don't be as stupid as</b> <b>some of the past ones.</b> <b>[Music]</b> <b>[Music]</b> <b>[Music]</b> <b>[Music]</b> <b>[Music]</b> <b>[Music]</b>
