May I please have suggestions for stopovers and sights? Family of 6 (3 teens and a 10 year old plus mom and dad). Catching a bicycling trip with Backroads in Jackson (Yellowstone and Grand Tetons) then driving back home to Chicago. Allowing for 3 days driving each way. Driving a 99 Suburban. We want to include Mt Rushmore. Where should we stay each night? What things should we stop to visit? We like interesting food and unusual sights.

Many thanks in advance.
