There are indeed some decent roads south of Indy in Brown County. However, they're more than an hour from there. I feel like Indy would be better than Chicago, but I'm equidistant from both, so it doesn't make much difference to me.
Copied from the other thread:
I don't know of any great spots, but there are some nice beaches in the south west of MI. Definitely room for cookouts, camping, and some nice sunset shots! The roads in the area are pretty good back in the woods, but I can't think of anything spectacular.
