Spring is a season that has many pleasant associations: first blooms, longer days, warmer weather, and when donkeys roam free in the streets. Umm, what?

That last bit is a true story set in the Colorado town of Cripple Creek. Every spring, this small American town sets a herd of 15 donkeys free so they can graze freely, much to the joy of locals and tourists. The day the herd is released the event is attended by a large crowd with a celebratory atmosphere.

While the current event is a happy one, the origins of the freedom donkeys is built on sorrow. Back when Colorado was a gold rush state, donkeys were used extensively as beasts of burden, working tirelessly underground and never emerging. According to the legend, then-president and early environmentalist Theodore Roosevelt visited the town in 1901 and took pity on the little donkeys.
