My suggestion (having been there/done that):
From Detroit take 90 west - it will take you to the Badlands/Mt. Rushmore and then further on to Yellowstone. If you're adventurous, get a county-level map of the Black Hills area and stay off the "highways". Head south after Yellowstone down through Grand Tetons and then continue south into Colorado or Utah, meet up with the WC Camp Commander, then come back either 80 or 70 (not much of anything along either of those interstates, but 70 was worse in my opinion). This is a good loop for a two week trip. Two years ago I did the Badlands/Yellowstone and back to Madison WI in 10 days/3000 miles.
