“Arizona has a deep history in Western sports,” said Casey Lane, general manager of the Arizona Ridge Riders, one of 10 city-based teams in the Professional Bull Riders’ rapidly growing league. Teams bull riding — five-on-five contests between city-based squads — didn’t exist until four years ago. Lane said Ridge Riders Days in Glendale draws roughly 30,000 spectators each year, with preseason events bringing thousands more. “Some Sundays, outside of the NFL and college football, bull riding is the most watched sport,” Giangola said. “Bull riding — and the Ridge Riders — give people a way to express pride in Arizona and the Western lifestyle,” Giangola said.
