Phoenix is hotter than Tucson, but I think it has better 2A representation. If you do move to Tucson, I suggest Marana (NW Tucson). Better schools than TUSD (I would move out of state before letting my kids go to a TUSD school). Sauarita is nice, too. If you look at Marana and want land, west of the town and north into Pinal county has some nice tracks of desert. We bought 3.5 acres on Dove Mountain (not IN Dove Mountain, but ON Dove Mountain) and just as the economy turned up (ya' know, when the last guy was president), the area exploded in housing. Just drive north on Twin Peaks from I-10.
Anyway, PIMA county is governance is a clown show that only mirrors the Tucson City Clown'cile. Otherwise, we love the state's gun & knife laws and it's diversity of flora & fauna. We're just hoping that the mass exodus of Blue Californians won't turn the state purple or blue... damn. Never mind
