VERY VERY COOL! To tell you the truth, Tacoma Mall was my one worry and something I haven't braved yet.
I have been open carrying around Tacoma for the last week or so though, so if you see another person with glasses, carrying a big ugly gun in a hip holster with a brown leather jacket, that's probably me......nobody yet has given me a look, except the lady in McClendon's HW @ Canyon Rd and 112th that rang me up the other day; she was staring at my .45 the whole time, but to her credit didn't say anything or even stutter.
Oh, and since it seems like there are a lot of people in the Tacoma/Puyallup area, if anyone wanted to get together for an open carry lunch or something one Saturday or Sunday around here, either at the mall or anywhere else, that would be pretty darn cool. I feel kinda weird being the only person around open carrying (my wife says it makes her uncomfortable that I do it, but maybe she wouldn't feel that way if I showed her it's more common than she might think....)
