I'm planning a trip to South Dakota with my 9 and 7 year old in mid-August. Places I'd like to see are, Badlands National Park, Mount Rushmore, Spearfish Canyon, Custer State Park, with possible Jewel or Wind Cave, Bear Country, Crazy Horse and panning for gold somewhere in there too. Suggestions on Itinerary? Thinking 5 day trip with camping. First night will be in the Badlands as that is about 7.5 hours from Minneapolis. Any other "must see's" with kids? Any help is appreciated!
