I was at the Wilsonville Costco store today during the lunch hour sitting at one of the picnic tables with my $1.50 hot dog and soda when I noticed a guy open carrying. I've never seen anybody OC in Costco before, and it took me a bit by surprise. I am 99% certain he was not a cop. He was carrying a stainless 1911 with walnut grips, (looked like a Kimber or a SA to my untrained eye) cocked and locked in one of the form-fitting hard plastic retention holsters. I have to admit I found it a bit unnerving when he walked over to a position almost directly behind me with his back to the wall. I wound up slightly shifting around in my seat so that I could see him out of the corner of my eye. Intellectually I knew he was probably just a law-abiding citizen choosing to OC, but I still didnt like him being directly at my 6:00 and only a few feet away. After a bit he walked over and joined an older man who was probably his father and they got in line with everyone else to buy a hot dog. I had the opportunity at that point to "people watch" everyone around him and see what sort of reactions they had to his openly carried weapon. I saw several people glance down at it, but nobody seemed surprised or frightened by it at all. I guess I was expecting some sort of reaction, maybe a Costco employee coming over to ask him to leave, but nothing of the sort happened. I found that to be a pleasant surprise.
