If you want to learn to ride like Flip -- or, more likely, just flip head-first off some livestock -- here's your chance. Each year, Lancaster's Rock-N-Roll Rodeo Gear sponsors two three-day championship bullriding and bullfighting schools at the indoor Bar W Slash Rodeo Arena in Aurora. Classes are offered for all ages and levels of experience, although 15 through 25 is considered the prime age for bull riding. Participants should have their own gloves and spurs;the school supplies the bulls, and there are enough for each student to have his own ride. The $350 tuition includes instruction from champion bullfighter Rowdy Barry and Fort Collins's own Mike Moore. The spring session takes place the first weekend in April, with upcoming schools planned for October or November.
