8 pm: Bull Riding

Who knows why people jump out of airplanes, try to jump motorcycles over ravines, or hop on the back of crazed 2-ton animals. But they do. And if you like to watch, then the DeWalt Challenge is for you. It combines the seasonlong score keeping of NASCAR racing with much faster events--ones that last 8 seconds, at best. These Professional Bull Rider contests skip all the namby-pamby bucking broncs, trick roping and barrel riding and stick to the really nasty injury-causing bull rides. Longtime world champ Ty Murray, “the Michael Jordan of bull riding,” will be out to get the bull riding title, but he’s got to beat young whippersnapper Chris Shivers, the 21-year-old leader of the Professional Bull Rider series.

* The DeWalt Challenge, part of the Professional Bull Riders Bud Light Cup Series, Arrowhead Pond, 2695 E. Katella Ave., Anaheim. 8 p.m. $10 to $100. Information: (714) 704-2500 Tickets: (714) 740-2000.
