This came up on another topic. But anytime us CCW guys/gals or any gun owner for that matter, see a private buisness post a sign on there store stating "gun free zone, no firearms allowed" inform the owner/manager that he/she is posting a engraved invite for the "dirtballs" that his/her sign excempts. I know it is federal law from carrying in government buildings (schools, post office, court houses etc.) But private property being up to the owner is his/her choice, but if we do our part and make sure it is "Concealed", he/she and their patrons have nothing to fear from seeing that evil gun. But they will appreciate the dirtball being stopped (hopefully without a gun fight)who comes in waving hers/his gun. Again, tell them that advertising no guns allowed is a serious mistake.
