Here in SC we would see such small signs as a "wink, wink" message meaning, "we're not going to enforce this stupid policy". To be legal, signs here have to be 8.5" X 11". As others before have said, concealed is concealed. I don't see most store owners attempting to pat me down with any success anyway. Also I refuse to fly because of the hassle and loss of rights. I'd rather drive than give up my rights. They can take their aiports, and air lines and shove 'em as far as I'm concerned. If I must fly, I'll fly private with my carry piece and without having my wife, daughter, or grandmother fondled. Where I am not allowed to carry, I avoid going or spending my money. Period.
