I am from wyoming and it is a great place to see. You will love it. There is a lot of long trails that you can walk on but if you are in a hurry you can see most everything from the road and from the close up trails. Old faithful has some intresting trails and is a great place to spend some time at. I agree that it is nice to stay at least one night in the park. Jackson is a really neat town with a lot of shops to look at and some good places to eat at. But is very packed in the summer. Have a great time. It is very beautiful!!!!!
