I have only seen one store in our area that had a sign saying "no concealed weapons"...and it is a local gun shop. Said something like "sorry folks, for insurance reasons". It is a well known shop; lot of hunters go there; they have a range, etc. I have not seen the sign at any of the other gun shops we go to. Struck me as odd. Has anyone else heard of the "insurance" reason? Is it common for gun shops to refuse CCW?
