Haven't lived in Amarillo, TX for a while but 66 used to go through the old part of Amarillo. Check out some of the clubs where the cowboys go. Sign will ask gentlemen to remove their hats and the furniture is bolted to the floor. 20 miles outside of Amarillo, on an interstate, is Canyon, TX. Check out Palo Duro Canyon, a few miles outside of Canyon. It is a miniature Grand Canyon and a state park and is a fantastic place to visit. You can camp there. In the summer it has a wonderful musical western show in a natural amphitheatre.
