The big issue for me is having to leave your sidearm in the truck because you cannot enter the business with those signs.
I've already had a pistol stolen once. Left it in my truck, went in with my wife to have a bite to eat. Chevy pickup. Didn't take’m but a minute to get in/out.
Nice one too. Nickel plated snubby .357 mag.. Damn I loved that there wheel gun. Now some gang banger punk is sportin it around. grrrrrrrr
I generally avoid stores that are gun free zones, and the potential of having your gun stolen from your vehicle is one of the reasons.
