I've been in tucson since June 6, and I've seen dove literally everywhere, and while making the trek between Tucson and Phoenix a few times I've seen dove the entire way. Not being from here and knowing the landscape, I can't say where spots are, but, there's plenty of agriculture along 10 between these two cities with a lot of desert scrup adjacent to it. It looks to me to be real good for some dove shooting!
I've never seen so many whitewings in my life!
