 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. Beginning with the very first one in 1864, colorful parades around the plaza have always been a big part of the Fourth of July celebration. The first horses were from Fort Whipple. Then in 1866, when the first recorded horse races were held in Prescott, cowboys on horseback joined the parade.
