Strange Tourest attractions between Montana and Virginia?

Me and a friend are taking a roadtrip from montana to virginia beach next week. we will be starting in Havre Montana, and ping through Billings Montana, Rapid City South Dakota, Mitchell South Dakota, Sioux Falls South Dakota, Sioux City and Omaha Nebraska, Kansas City, St Louis, and Louisville just to name a few. Does anyone know of any strange, tourest attractions along the way? Haunted Landmarks and things of that nature, but really any tourest attraction that is out of the ordinary!
