The other show in AZ is the Quartzite show.
Just a little show that sprang up out in the desert. A few snobirds, (them's
anybody that don't like snow) parked their RVs in the desert near Quartzite &
started selling rocks they found swap meet style. It grew like topsy & now there
are estimates of 30,000+ RVers every year. Bring a tent or RV, there's no
h/motel in Quartzite; ya gotta stay in CA (about 50 mi, I think) & drive over.
Haven't ever been, but hear you can find about anything in the lapidary area.
