Reflecting on this, I wonder if my history is part of why I feel more comfortable with the thought of practicing open carry than concealed carry. To me, open carry is natural. I grew up doing it. I didn't carry daily, but if we were out at the range, we got to wear the guns from the time we left home until the time we got back. And that typically included stops for snacks at the Handee-Mart or a visit to the grocery store on the way home. Pre-teens, and their dad, walking around with sixguns in holsters at the Piggly Wiggly never merited a raised eyebrow. A 12-year-old walking down the side of the road with a shotgun or rifle never resulted in the authorities being called. Hell, the number one fashion accessory for a pickup truck was a gun rack in the rear window, complete with the mandatory truck rifle! People had guns, same as they had dogs or shoes.
Concealed carry, though, seems to me like you're trying to get away with something. There shouldn't be any need to "get away with" carrying.
I know, I know, there are differing school of tactical thought. I'm not here to argue that. I'm just doing some self-reflecting, realizing things about my psyche and attitudes, and how those were probably shaped by my life so far.
