Own a donkey in america? Answer only what you know.?

can I own a donkey? Is it legal in New Mexico? How much food does a donkey eat, and how much water does it require per day, or whatever? can you direct me to a site about donkey care? Are donkeys expensive to buy, and where exactly would I buy one? Can a donkey stand up to desert temperatures? Can a donkey be ridden? And finally, can a donkey pull a cart, or hold a small load on their backs? thank you!
