I don't know if you've seen this site, but it lists gobs and gobs of rides in So Cal...though nothing in AZ. I wonder why since it includes UT and CO?? Anyhoo, in the event you didn't have this site, I thought I'd pass it along (and in the event you've already seen it, well, maybe someone else hasn't). When I lived there closer to the Pacific Ocean I used this list to plan my summer!
