I would just like to report that, after reading this thread, I have been happily OCing everywhere I possibly can for the past 2 months, and I've had exactly 1 person I don't know mention it, and that was just to ask if it was a Glock (which kind of betrayed her ignorance because if she'd ever seen a glock, she'd have known it was not). I often OC at Menards when I take my 2 year old with me to buy manly outdoor stuff, and the checkout girls still smile and chat and with us and don't seem to mind one bit that there's a gun on my hip.
