I tend to agree with leemozoid here. I've seen several guys open carrying here and there. (Funny, haven't seen any women doing so ... hmmmm??) I'm not sure the general public even notices to tell you the truth. Only reason I do is that damned GC ... If I hadn't married him I'd still be blissfully unaware of my surroundings ... sigh ... Now I'm OCD (and it appears to be a permanet affliction) about exits and where they are, sitting where I can see the door and taking mental note of everyone I see ... It's tiring ... But necessary, I suppose ...
