Hi Dave, I did some research and it appears that the closest dstar repeater to you is K8LCD (147.210+) in Hell, MI. It claims to be a wide area coverage repeater, but I expect that you are too far away from it. If you have a 2m yagi and its up on a decent size tower, you might be lucky enough to get in. I believe that is wishful thinking, but hey I try to be an optimist.
I'm surprised that there isn't a group in the Detroit metro that doesn't have a dstar machine. Hopefully, some of the ham clubs there are planning to do dstar but I have no idea. You might consider getting a DV Dongle for working dstar. There a lots of them on the air and they work great!
As far as having a forum page for each state on this site, I don't think there is enough activity.
Good luck and 73,
