i think it's more than 1 percent. maybe 3.5%. ha.
i'm right there with you...being in florida, i can't open carry.....but when i visit any of the other 43(now 44) states that don't prohibit it, i open carry. unless i'm wearing gym shorts. which in an open carry state, i try not to do.
i don't do it for "attention", nor do i carry a voice or video recorder around with me at the ready. (well, my phone is both but..)
i have read stories on here where people were minding their business open carrying, not for attention, and have been harassed.
