AZ - Pump Station Road Dispersed Camping
Free, primitive camping surrounded by mountains in the Ironwood Forest National Monument. Tons of spots for RVs, etc. We spent three nights here and would stay again.
There's a small airport near here that tows glide planes up and releases them. It was neat for a while but I eventually had enough of the small prop engines.
