Questions About Circumnavigating Lake Michigan

Midwest Beach Vacation

Circumnavigating Lake Michigan by road. What to see? Where to stay? The boyfriend and I are planning to drive from Champaign up to Chicago and then on around the lake the week of July 4th. We'll head up the west side and go all the way around. What shouldn't we miss? We have tentative plans to stay one night in Milwaukee with one of his relatives and to go to the Safe House, and then to stay with friends for a night or two in Whitehall, MI, towards the end of the trip. Toss out any suggestions you have. Our interests are broad, but include both natural beauty and man-made weirdness. Last summer we hiked in the Rockies and came back by way of Carhenge and the Corn Palace.
