Thanks for all the input! We wound up hitting the Superstition Mountains, and my wife hit the botanical gardens (while I was off doing my day job) though she had a microdrive failure while she was there . Thank heavens for Fry's electronics in Phoenix.
The Superstition moutain area was beautiful! We both have a ton of photos to weed through, but here are a couple of mine that I really liked on the first pass through.
P.S. The Mahi-Mahi burritos at Rubios were great, too.
