I live in Phoenix. I see people open carry a couple times a week all over the place. Once I have a carry firearm that I'm happy with and have properly trained with (gun show in two weeks!), if I'm working on a project and I'm just going to run to the store or something, I'll probably just slap on a belt holster rather than put on a concealed rig.
I definitely will open carry when hiking. Too much of a pain otherwise.
Open carry in Arizona is legal with no paperwork, by the way. Huzzah!
Edit: besides, holsters are cool!
