I love driving through the Bighorn Mtns on 14A. It is not for the faint of heart but if you know how to drive in mountains, it is not bad.
I also love driving the Beartooth Highway and Chief Joseph highway. The Lamar Valley in Yellowstone is a great place to do some critter watching. Last September me stopped in the Lamar for a couple of house and saw wolves, grizzly bears, moose, hundreds of bison and elk, and a few really nice mule deer.
We are going back to this area in September because I am suffering from withdrawal from seeing the mountains.
