Out here in AZ, no one wears masks unless their employer is forcing them and I even heard a nice old dude arguing with his manager at Home Depot about how dumb it all was and just to let him wear it around his neck.

At the post office they have signs that say they will kick out anyone not in a mask, but they don't. Probably 3/4 of the people in there the last time I was there were not wearing them.

Requiring vax cards out here would not go over well, at all.
