I had the horrible luck of seeing one in laredo years back... it was one of the most gruesome things I've ever seen!!! Especially when I found out the girl didn't volunteer for it... Most of the time the girls are "given" to the brothels there by their family for money, or are sent there by their family to make money, 15 year olds, etc... when a girl is caught stealing part of the mexican mafias share, they're made to perform in a donkey show, where they harness one to a donkey. the donkey basically ruins the girl, there's a bloody mess, and the girl is unconscious when it's over. They drag her off stage and mop up the blood. She's usually disformed for the rest of her life. It's the most disgusting thing ever!!! That's why it's so hard to find, girls don't always steal the mexicans share of the money!!!
