Found this interesting and happen to come across this in the local paper…
Burro Days (Get Your Ass Up the Pass!)
Fairplay, Colorado
Quick! What’s the only sport indigenous to Colorado? That’s right: pack-burro racing, in which competitors lead (not ride) their burro companions along mountainous paths. The pace of individual competitors can range from a flat-out run to a stand-still (stubborn as a __), but it’s certainly a physically demanding competition in high altitude.
BTW, this is not very far from Taylor Park if you’re in the area.
