Yep, we rescued a couple burros/donkeys/same thing less than a couple months ago. We were gonna' get mountain bikes but ended up with these totally feral fruitcakes instead.
I pulled these 2 right out of the "killpens" down in Texas. I got these 2, that will kill you easily, but all the mustangs and burros in the picture with them were dead by the end of the day. Mustangs, donkeys and what not over produce on BLM lands so they get exterminated every day.
Pack Burro Racing has been going on in Colorado since 1949, every year. There's about 10 races from 5 miles to 29 miles, NO you don't ride the burro. you drive them.
Our little slice of heaven. We're all into the cardio thing now.
