What Great Lakes City Created an Ecological Disaster in 1986?

What Great Lakes City created an ecological disaster in 1986 when they released 1.5 million balloons in an attempt to set a world record? I don't think anybody in the room has come up with an answer yet. Cal, you come a long way from the Great Lakes region. The rest of these folks, they should whoopi on this question, but it seems like they're not going to see it. He's on the Great Lakes, man. That's why it's a good question, Brody.
