Lyrch, there isn't too much out here...right now. Of course, the big one- Prescott was last weekend. That rally is presented by Phoenix local rally promoter Bill Barfoot. Bill has done much for rally in AZ. He organized a RallyCross series at Canyon Raceway, but attendance was sketchy. The series was cancelled for this year.
Bill is quite the webmaster. You can learn more about the ARA (Arizona Rally Association) at the following: TimTheDriver
