I see none in NE Tx DFW, maybe in the piney woods but they always did that there.
When I got here everyone had a gun rack and long arms in the rear window of the pick up truck but no one walking around with a hog leg on the hip.
I will say this for open carry.
No one is going to rob the stockmans bank when every depositor there doing business and every teller is wearing a hog leg.
