Somewhat OT, but FQ is absolutely right about Tex-Mex and the high quality Sonoran-style food available in Tucson. I'm headed to AZ for the annual pilgrimage to the aged parents' homestead. I'm a little worried about the anticipated weight-gain, but that's what New Year's Resolutions are for. The REAL Mexican food available throughout AZ is maybe the best in the world. Cooked by genuine Mexicans using better quality USA ingredients. What a combintion.
On our Aussie's new place of residence--Adelaide is cooler and much wetter than Tucson. And, they call it the City of Churches. Tucson is a University Town and would be more accurately called Sin City. And, it's hot for most of the year. Yeah, it's a "dry heat" but so's your oven. Would note though that on last year's trip we hit a little snow coming into Tucsonin mid-December. Not enough to stick, but enough to make my hands cold even with my pigskin gloves on. He might like Flagstaff better--except for the "near the water" part.
