I need advice re: a last minute road trip. My two brothers and I will be traveling from NC to Rochester, Minn leaving tomorrow (5/26), arriving in Rochester on 5/29. I think we will hit the road hard tomorrow until Lexington or Louisville, KY, travel to Chicago, IL, and spend a bit of time in Wisconsin. Any suggestions/preferences re: routes and things to see along the way? I have been to Chicago a couple times and Lexington, but would appreciate any insider info. Thanks!!
