This year marks the 112th Cheyenne Frontier Days rodeo and western celebration, held annually in Wyoming. It is the largest outdoor rodeo in the world and it's clear why the festival attracts such a large crowd: over one million dollars is awarded to contestants each year. With that kind of prize money at stake, the best rodeo athletes in the world continue to return to the "Daddy of 'em all."
