Only a couple of places in my area don't allow it other than the usual places like Banks, P.O..
One is the movie theater, they have a sign posted at the front doors.
The other is the COOP main office building. WHY?? This one really bugs me, this is a coop office building, their customers are farmers and ranchers, both of who I think usually carry guns, either long guns or hand guns of some kind.
I think there is another place around here, but I have never done business with them, nor will I want to.
As of right now, none of the department stores, grocery stores, convenience stations, restaurants, etc. have the No Weapons sign on the doors.
I will have to check out that site.
