I was going to guess rock candy. Arizona is my state of birth (Bartlett Dam, near Cave Creek), but I only lived there my first year (until the dam was finished--my dad was a concrete worker). I do have some nephews in Phoenix, though, so visit there occasionally.
We have something in common David. My Dad was welding foreman on a dam project in Paonia, Colorado, on the North Fork of the Gunnison River. We too moved soon after. I have dear friends in Cave Creek. We visit there for several weeks each winter. We also have access to a condo in Sun City... so know the area well.
