We are planning a trip to South Dakota & Wyoming in mid August 2010. We plan on stopping @ Badlands, Mt. Rushmore, Custer State Park & Yellowstone/Tetons. Interested in any recommendations--including daytrips, scenic drives & good food from your experiences. We enjoy backroad trips to out of the way places for views, scenery and dining. Three adults--no children. We are driving from IA to WY and then back thru SD.
