re: Mt. Rushmore - Yellowstone - Grand Teton trip

I've come into Yellowstone from Montana before. And left through 14/16 to 90. You can't go wrong either way. Montana is more attractive, but once you get into the mountains of Wyoming, it's hard to compare.

You can't go wrong either way to get there.

Mount Rushmore is not a time consuming thing. May have spent 20 minutes there, but I was by myself.
