Welcome to the forum and welcome to OC'ing.
I've been carrying one of my three handguns wherever I go everyday since I decided to just 'go for it'. To my surprise, there is very seldom any reaction from anybody at all. I've just gotten back from King Soopers where I had an encounter with a security guy and he was a total breath of fresh air: "I'm glad to see somebody exercise their 2nd Amendment rights!" That was typical of things he said, and I was blown away by his positive attitude.
Anyhow, most folks don't pay much mind to a properly holstered weapon carried by a law abiding citizen. I am waiting for my CCW, which I hope to see in about a week or so. Until then, and likely long after, I plan to keep on OC'ing.
It is also refreshing to hear of a pair of young fellows who carry responsibly and safely rather than reports of young people who we hear so much about engaging in illegal behavior. Good going to you boys, and glad to see you here on the forum!
