Not uncommon around Kingman, AZ. Mostly it's the rural folks in town on business but a couple townies open carry as well.
On the one hand, I get not wanting to make folks uncomfortable and being a conspicuous target, but on the other hand I sort of feel it's part of the "old west" the tourists are coming through to see, I want others to have the option, and let's face it, it's amusing to be able to comment on someone's sidearm just you would a nice pair of boots or whatever and not have the only place to show off one's toys be this forum.
I suspect the tactical disadvantage is reduced around here since between the area and constitutional carry in AZ, you assume even if you can't see one, it's there.
My personal rule is, if you carry, carry something classy, and of course be extra courteous and dress up a little, since if you open carry your behavior reflects strongly on all gun owners.
