Under the wide open skies of Wyoming, Professional Rodeo Cowboy Association tie down roper Wendal Hearn leaves the roping box in pursuit of the calf he drew in his second round at the 112th annual Cheyenne Frontier Days Rodeo in Cheyenne, Wyoming on July 20, 2008. Cheyenne Frontier Park boasts the largest rodeo arena in America, with a length of 700 feet and 200 feet wide. To give the advantage to the stock, the Cheyenne rodeo utilizes a 30 foot score line in the timed events. Cowboys must remain in the roping box until the calf has advanced 30 feet down the arena before spurring on their quarter horse to make up ground. As was the case on Wendal's run, the 30 foot lead is simply to much to overcome and a cowboy takes a no time. The rich western custom of rodeo in Cheyenne consistently draws the worlds best contestants each year during the last full week of July to test their skills in the time honored traditions of the American Cowboy.
