I took the most beautiful drive the other day on highway 212 in Wyoming. It was amazingly beautiful. Each turn had something new to look at. If you have the time, this by far is one of the most beautiful drives I've ever been on. At the top, you get a stunning view of bear tooth mountain.
On the way down towards Montana, I stopped at another viewpoint and the chipmunks were the friendliest I've ever encountered. They were all too eager to ham it up and be in my photograph. One looked like he took pleasure in photobombing my shot! It really was a beautiful drive and I would recommend making a trip if you've never been.
