I shot in Phoenix and surrounding areas many times. I found a neat places on the South Mountain and there is a cute stone house at the bottom of the mountain adjoining the Scorpion Gorge. Next to it is a horse stable where you can rent a horse and have a western style shoot with a model. There is also a local model, Jill V, who showed me around the new locations you may want to contact her, just tell her Johnny O from Chicago sent you, her link: http://www.glamourmodels.com/cgi-bin...s.cgi?ID=JillV
There is a local Arizona forum you may post your inquiry on, I'm sure some local photogs and/models will respond, here is the link: http://www.arizonashoots.com/forum/
Post some images when you get back from Phoenix. Image below is of Jill V between the Salt river and the Superstition Mountain east of Phoenix.
