Businesses in PA cant post signs banning CCW....even if they do, they are legally meaningless.
I have never seen a sign of any kind saying I wasnt allowed to carry, however, I do know that there are certain chains that do not allow weapons in their stores....and you know what...I carry anyway.
The absolute worst thing that could happen is, I would be asked to leave..and this of course assumes that someone detects that I am carrying, which would never happen in the first place.
Way I see it, the only way anyone will ever know for certain that I am carrying, is if I had to deploy the weapon....and if I ever do.....my justification for using deadly force should be enough to defend myself against a tresspassing charge.
I will carry any place that legal...and I dont give a shit what some store manager says.
If it aint against the law...I will be armed there.
