There are still cars in MI. I just got my 69 out of a buddy's barn in Battle Creek, MI after sitting for almost 10 years. He also has his 68 Dart in there, if he ever finishes it.
Should be coming up again this year. Wish I could go, as I have my 69 'cuda to work on. But, I'm living in Indiana now. Always a good show, swap is good but sky-high prices for stuff.
