It's a little late to be looking to go on a vacation, I know, but this is the only time available my b/f and I have! I live in SE Michigan (near Detroit) and I'm looking for something no more than a 5 hour drive from us. I had an idea of going to NW side of the state to the Sleeping Bear Dunes or to Niagara Falls. Any other suggestions? I don't know if there's anything cool to the south of me. Preferably something nature-y (no big cities).
