About a year ago, a friend of mine, who just moved to Las Vegas, was riding through Red Rock Canyon National Park
It is a beautiful place to visit, so if you haven't been there, it is worth the trip. Anyway, my friend was busy taking pictures and enjoying the sights, when all of a sudden, a wild burro stuck its head in the car window! He was quite surprised but was able to get a picture of the donkey before it turned around and went on its way. I don't know if the burro was looking for food or just welcoming the newcomer!
