I rip the sign down where ever I can and throw it in the trash. And I don't know of any place has replaced the signs where I pulled them down. Obviously I don't do it to state or federal property because those are gun free by law, for now. Privately owned public places like malls and shopping centers with zero security yeah. The way I figure if they can't stop some one from ripping down their stupid sign then they sure as hell aren't going to stop some maniac and/or terrorist from walking in there.
