buell riders in or near murrieta,ca?

Answer 1

You must mean Bull riders...

If you are asking if there are professional bull riders in the area, the answer is yes. The Valley News has a story that says

"12/8/2006 7:15:17 PM

Quail Valley’s Bobby Waller qualified for the California Finals Rodeo in Bull Riding while Murrieta’s Rachael Ross and Temecula’s Virginia McClintock both qualified for CFR in Barrel Racing."
It goes on to talk more about the California Finals rodeo.

If you're looking for where to ride some bulls yourself, I would check ask at a local feed store - they will know who's riding, when the local bull riding events are held, and in general, who to talk to. You can also try the realtors at this specialized group of horse enthusiasts (http://www.socalequine.com/eqbusiness/real_estate_agents.htm)
