This topic came up on another thread and didn't know what the anwer was. I work at Costco they have a sign out front saying firearms are not allowed. Now just saying you go shopping with your wife and you are carrying which is your right you have your CCW and all everything legal. Can you legally bring the handgun in the store? I'm sure people do all the time but, is it legal? I can't see how they can tell you you can't if you have your CCW.
