In better times: Jimmy "Stretch" Borunda, 30, a bull rider from El Paso, Texas, prepares for his event at the Del Rio Rodeo on July 7, 2007. He went on to win the bull riding competition. Amateur bull riders across Texas compete in small-town rodeos where their sport is often the highlight of the night. Bull riders risk life and limb for rewards of around $1,000 for the winner, and they often claim to have riding "in their blood." From the series: "Thirst for Grit - Rodeo Bull Riders."
