We intend to visit the States for 4 weeks either this summer or next. We want to spend a week in the Chicago area and then rent a car for a three week road trip, returning to Chicago. The obvious choice would seem to be a circle of Lake Michigan and there is a lot of info and advice around on that. I'd like some ideas for alternatives so that I can weigh up options before making a decision.
We would be travelling with a 13 year old and are looking for outdoor activities, small town America etc.
Thanks in advance,
