 SalemNow.com. That is SalemNow.com. This is J.C. Trujillo. In honor of Danny Freeman, Frontier Days historian, KYCA presents another Frontier Days story from his book, The World's Oldest Rodeo. Wild cow milking was a popular rodeo sport in Prescott from 1936 through 1981. The spectators loved the excitement and drama. It took three cowboys, a roper, a mugger, and a milker, who milked into a Coke bottle and raced it to the judge. The cowboy with the fastest time won.
