I've been thinking about this today and other than BassPro Shops, I can't think of anywhere I've been in the last few years that has been posted. BassPro doesn't say "No CC", just "Please check sidearms at the counter"...
As I said, I left a gun show because the SP were checking firearms and chose to go back home. Other than that, I go to restaurants, bars (don't drink), shopping, etc....and carry nearly everywhere other than those areas that are federally mandated as off limits. I have not been to a moving picture show in some years now. I took the kid to the "Lord of the Rings" trilogy three years running so that's been at least six years.
Maybe I should pay closer attention, or not!
