Most people don't care. Those that do usually have enough sense to realize most people don't care.but if anyone else in the large crowd even noticed his gun, they CLEARLY didn't care....of course it was in Teller County.
A couple of weeks ago I was OCing in Manitou Springs, which is a magnet for non-Coloradoans. I saw more heads turning that day towards my firearm than I'd seen throughout the entire month of carrying around town.
I could almost see the dotted text balloon above one woman's head: "Omg! He's got a gun! Is that legal?" and her bf/husband's response, "Shh, don't worry, honey, we'll be safe when we return to New York..."
