I will be backpack camping, though I'd like to find someplace I can park my car and have at least a reasonable expectation that no one will smash my windows and steal my stereo. Wind Cave sounds like a great place to start, with Black Elk as my reserve site. The plan is to spend three days in the wild, a fourth seeing the monuments and museums, then head back on the fifth morning. (Though like all plans, they can change as the situation develops) And yes, I am planning on doing some geocaching. Thanks again for all the helpful links and info. I'm really looking forward to this trip, especially being presently in the grip of an Ohio winter. It gives me something to focus on and feel warm while I'm chiseling my windshield every morning. )
