This is Tonya, Tombstone's Celebrity Mule. That's me in a parade riding her on Allen Street, the main street of Tombstone, where Wyatt Earp and Doc Holliday used to hang out. She's a 24-year-old mule; her mother was a Quarter horse and her father was a donkey.
Mules are truly awesome animals. They have great eyesight - in fact, they have the largest eyes of all land animals. Their eyes are off to the sides of their heads which gives them great peripheral vision. There is an old saying: "As stubborn as a mule." However, they are really just looking out for themselves. A person can overwork a horse to the point where the horse will die, but a mule will just stop when he's worked hard enough and lie down and refuse to do anymore until he or she has rested. I don't call that being stubborn; I call it being smart!
