I'm torn on this. On one hand, OCing should be something that doesn't spook the sheep, and being sheep the best way to accomplish that is to desensitize them through conditioning... seeing good people with guns doing good, normal things.
On the other hand, I don't want to put myself at the top of the list if I'm in a gas station and some asshat decides to rob the place. Previous incidents and common sense have proven that authority figures... security guards and such... or people that pose a threat are usually targeted first in bank robberies and similar incidents. I'd rather be able to slip under the radar and if I feel I should act, to be able to do so unexpectedly and without any indication or warning to the bad guy.

I do open carry when I walk my dog at night or when I'm in the mountains (not just camping, but if I drive through the mountains and stop at a gas station you might see me OCing). However, 95% of the time, I'm CCing.
