My fiance and I are heading to South Dakota for a week. We're going to be camping in a tent in the Keystone area.

I've got all my gear ready to go, but we're not really going to be "roughing it" on this trip.

Does anyone have any suggestions for places to visit outside of the big ones, like Rushmore, Crazy Horse, Crystal Cavern, Devils Tower, Deadwood, the Badlands etc?
