This weekend marks the 145th reprise of The Greatest Two Minutes in Sports. Many of us will watch thoroughbreds earn their costly pedigree at the Kentucky Derby. While we celebrate these purebred horses for their agility and speed, horses in Colorado were largely obtained from wild herds of mustangs that were caught and domesticated. Wild horses and cowboys have long represented Colorado and the rest of the American West on the covers of western pulp books and magazines and in the minds of people all over the world. Historically, horses in the West have had more practical purposes than the status symbols that run at the Kentucky Derby.
