The only chance I ever got to carry openly was a visit to Taos, NM - and it felt good. Armed without worry ("is it hidden? does it show? is it legal?") is a good thing.
So long as I was sure I would not be detained for doing so, YES I WOULD CARRY OPENLY.
Yes, there is an argument for not scaring sheep, and not letting perps know who is armed.
There is also an argument for getting the sheep used to the situation ("gee, he's got a gun - and nothing bad happened!"), and letting perps know who not to mess with ("he's not a sheep; let's go find easier prey").
Concealed carry supports a culture of fear: your fear you might be "made", your fear someone might find out and freak, sheeple's fear of guns when seen (they only come out when bad things are about to happen), sheeple's fear that someone might be armed, etc.
Open carry, given time for the sheeple to get used to it, eliminates fear. You don't worry about carrying, sheeple don't get scared from seeing guns, even perps simply move on to a safer target (like an unoccupied car).
There is a reason concealed carry used to be considered bad and open carry good: only perps hid their power, and gentlemen wore it proudly.
Let's return to that.
