Not another open vs concealed carry thread. :banghead: (Where's that beating a dead horse smilie?)
Responses will usually vary based on where the person lives. People who live in states that allow open carry (e.g. AZ, VA, CO, AK, VT, and some I'm unaware of - EDIT: these are states that allow permit-less open carry) will say that open carry is peachy, and there's little chance of being hasseled, even in metro areas. They also will say the sheep rarely even notice and if they do they probably won't care. I'm one those.
The other side come from states where open carry will get you thrown in jail before you know what's happened. They'll claim that open carry makes you a target for criminals (take out the opposition first, etc) and that all it'll do is frighten the sheep. They'll go on about how bad it is tactically to open carry, what kind of Rambo wannabe are you to open carry, etc, ad nauseum.
Bottom line is, there's tactical advantages both ways (if open carry was so bad, tactically, why do cops open carry?). There's also tactical disadvantages both ways. What you choose to do should be dictated by the laws of your area, the circumstances you're in, what you are comfortable with, and where in the balance of tactical advantage you want to be.
For me, I have a CCW permit, though I lack a good gun for that - at least during the non-winter months. Open carry is legal and reasonably accepted so if I happen to be open carrying I don't worry about it. When out hiking/hunting/camping I open carry simply becuase it keeps the gun more accesable should a bear/coyote/goblin pose a problem. In town, if I had a CCW piece I would conceal, if not open carry works fine.
