LOL!
I do camo most of the time! (And yes, sometimes I get “looks”.)
However, for the most part, my observation is that most people aren’t paying attention to anything at all. They’re all just wandering around in their on little world. It’s usually just us gun guys that can spot a carrier.
Probably 99.9% true.
My Friend (US Army Tank commander) says the same thing.
He says I watch everyone, and they rarely make eye contact.
If you get in the habit of Open Carrying, you’ll find that most people don’t notice. And those who do notice generally don’t care.
