Might I suggest camping here.
From Phoenix:
-Take 60 East to 79 South
-Head South on 79 for 5.3 miles
-The "flag pole" parking lot is on the left
-This is the start of Cottonwood Canyon road (dirt road)
-The turn is about .3 miles past mile marker 146 (when heading this direction)
-Once on Cottonwood Canyon drive about 3 mile down and look on the right hand side for a big open area set back off the road. That's would be the 1st choice for a good camping spot. If it's already being used head down the road about .25 miles and look left that would be the 2nd good choice. If you go past a fence, you have gone to far.
A little info:
If you haven't been out this way before, the last stop for food is the Bashes in Gold Canyon and the last stop for fuel is a Texaco (I think) that has a McDonalds in it. It's also located in Gold Canyon. *FYI-Gold Canyon is the stretch of 60 between Florence Junction and 79.

I don't know what I'll be doing then (work related) but if I'm around I'll be there.
