I'm in the Des Moines area. There are a couple of hangouts around here where muscle car owners and admirers get together once or twice a week. I just haven't had the opportunity to go yet. In fact, I had planned to go last night but the weather was cooperating. There is a big car show this weekend (The Good Guys Heartland Show) at the fairgrounds with over 3000 cars. I plan to visit that and take lots of pictures.
I'm sure I'll find some local people willing to offer advice once I get out there. Just want to say again how much I appreciate all the help everyone has offered here.
