Well, even though you had a nice time, I just have to point out that you were slumming. The really good bits of Michigan are farther north. I recommend all the coastal areas along Lake Michigan, Lake Huron, and especially Lake Superior. The northwestern part of the lower penninsula, just north and east of Traverse City, is spectacular in the summer and more spectacular during the autumn color season. (Not bad during the snow if you’re a ski bunny, too.) The upper penninsula is even better. Go in summer or early autumn, when you can be lazy and take your time. The coast of Superior is magnificent, little towns, lighthouses, sailboats, friendly people, and real history. Don’t miss the giant virgin stands of white pine on the Keeweenaw, or the college culture of Houghton. For history you can’t beat the little towns up there, and for industrial ruins, the failed mines and factories crumbling back into the earth.

Then there’s Sault Ste. Marie and the locks, which must be seen by boat. Spring for the boat tour, you’ll like it. If you want to see real wildlife, Isle Royale National Park in the middle of Lake Superior is a must. Moose and wolves! (But that takes a week in itself.) For pure history, try Mackinac Island. That’s just a good solid day trip…
