In 1940 the first One-Shot Antelope Hunt took place on opening day of the season near Lander, Wyoming.
It was conceived over a campfire by hunting friends Harold Evans of Wyoming and Hank Dahl of Colorado.
Hunters only have one shot at fast-moving pronghorn to honor a time when hunting weapons were more primitive.
The first competition was between teams from Wyoming and Colorado. Now personalities from around the nation participate.
The evening before, hunters hear the legend of the hunt and become blood brothers of the Shoshone Tribe. They receive an Indian name, a sacred medicine bag, and their bullet is blessed for the hunt.
