Whooo boy . . . that's in Cave Creek!
When I first moved to Arizona in 1962, we camped out at the campground in Cave Creek. It was a very cool place as campgrounds go. Nowdays, Cave Creek is the unofficial headquarters of the Hell's Angels.
AFAIK, it has been so ever since they chased Sonny Barger out of California. Fresno used to have a big gang of them here, but the cops pretty much chased them out years ago, and all the gang crime now is Mexicans and Asians.
