My wife and I are setting out on our big tour this June. We're following Adventure Cycling's TransAm route from Oregon to Yellowstone, then planning to cross Wyoming, S. Dakota, Minnesota, Wisconsin, through Michigan into Canada. Then we'll head down the Bruce Peninsula to Niagara, and finish on the Northern Tier to the Atlantic and then south to DC.

I'm looking for route suggestions from Badlands NP to N. Wisconsin (we're visiting family near Rhinelander). We've got plenty of time, so the route doesn't have to be a straight shot. Suggestions on interesting places to visit along the way are welcome. We're touring fully-loaded and camping.

Thanks for your input!
