Often called the most dangerous event in rodeo, the PRCA Xtreme Bulls bull-riding event helped kick off the Douglas County Fair and Rodeo Aug. 6 in Castle Rock. Douglas County High School graduate Patrick Geipel, now of Westcliffe, got the crowd going with the first ride of the evening. He was followed by pro riders from throughout the West, and a few from Hawaii. But the pros weren't the only ones riding. Aspiring cowboys and cowgirls had the option to take their shot ringside on a mechanical bull.
