Good article. I'd like to correct something, however. Quarter Horses are called sorrel when they are red like Doc Bar, not chestnut. Since he was a registered Quarter and not a Thoroughbred, which breed does use the term "chestnut" for red horses, I felt a comment was in order. Chestnut usually refers to a horse with a darker body color and a much lighter mane and tail, such as a palomino. Enjoyed reading about him.
