Yeah, well, we shop there... same as we shop at the mall, and go to the movies. F*** their signs, they're not scaring us off. We have as much right to be there as anyone else.
I hear that, I carry every time we go to Costco, they don't need to know a @@@@ thing. On a side note, took my little guy to the doctors this morning, walking right by a "no firearms allowed" sign. Had my Glock 21 on me and nobody but me knew I had it. Hell with those signs, I'm packing, sign or no sign.
