Donkeys have been loyal beasts of burden for 5,000 years, yet they still don't get a lot of respect.
In the wild, burro herds are a nuisance. In captivity, they can be mistreated. But in recent years, donkey sanctuaries have sprung up across the country. The largest among them is Peaceful Valley Donkey Rescue, outside of San Angelo, Texas, where the air periodically erupts with the unpeaceable sounds of donkey braying.
