Every spring we drive from WI to the Panhandle of Florida and like to make stops along the way. Any suggestions on interesting places such as parks, small towns, etc. to visit? We've been to Indy several times in the past and enjoyed an afternoon last spring in Madison. I've heard some interesting things about the architecture in Columbus. Any ideas? Previously we've made side trips to Highlands, NC, St. Augustine, Hilton Head and Lexington but this time, we'll just do a two night stay, leaving one full day to explore somewhere. We like historical sights, hiking or just interesting stuff. Any ideas?
