Got a family road trip planned from KC to MT and planning on seeing the Badlands, Mt. Rushmore, Crazy Horse and Deadwood, SD, Devils Tower and going over the Bighorn Mountains in WY, visiting family in Bridger MT and boating with them at Bighorn Lake. Probably going home through Denver, CO and don't have any stops planned on the way home. If you had 2-4 hours of extra time, what other attractions/points of interest would you recommend on the way up or back?
