Hey Bob your right, for those that have never been to Az it's only that lower southern part of Az that stays warm in winter, and area's like Flagstaff North gets lots of snow. It's a strange sight to see snow in the Dessert with these catus sticking there thorns upwards through that cold white stuff. Same weather applies for much of Cali it's only that small slice of Southern Ca over into Az that also stays warm through winter. But then again where else can you walk the beach and look back Eastwards and see snow clover mountains.
As for Rust your right again. Because even in the Dessert area's cars will be sun backed but only surface rust. A bug could sit out there for 30 years and a have about the same amount of rust that a car woul dhave here in only 3 years. I think it actually has more to do with the amount of dampness in the air that causes most rust. Most of my cars are So-Cal / Az Cars, thus rust Free! :icon_sunny:
