On a trip to Colorado I was sight seeing around a state park. I happen to come across an equestrian camp ground. There were a few horses in the corral. I stopped to talked to the owners who were camping there. Suddenly I saw this horse on the ground. Guess he was scratching his back? I had never seen a horse doing this. It was a lot of fun painting this. I know I had a smile on my face the whole time I was painting this horse.
