Ah, yes, the mountains would be different...does it ever stay freezing thru the whole day or just at night?Oh yeah, we can get pretty cold in the winter (in relative terms for Tucson..lol). I'm actually on the outskirts of Tucson and about 1k feet higher so we don't get the city heat and get full wind exposure. It snows a couple times a year here and we have plenty of hard freezes, but nothing crazy like Michigan!
