funny that this thread has cropped up while I'm sitting in Grand Teton
and was in Yellowstone two days ago.
The flight out from Wisconsin took us just south of Rushmore and Crazy
horse. Once you hit Rapid City, the trip becomes very scenic and the
country becomes very rugged. got upto 14,500 for a little while (on
oxygen) crossing the mountains east of the Tetons and diverting around
the fire TFR's, then a quick drop down into the Jackson hole valley.

I'd be up for considering a return trip.
