We will be on a month long road trip and need help planning this portion of the trip. We will be coming along I90 from Sioux Falls and plan on stopping for the night in Rapid City. Should we make a detour through Badlands on our way to Rapid City, and is this a feasible place from which to explore the Mt Rushmore, Custer State Park area?
We will be moving on to Yellowstone after our visit in South Dakota and would like suggestions on the best way to proceed through this area and on to Yellowstone.
Thanks for any help.
