I haven't been to a gun show in many years, and never since I moved to WA. I have conducted many home or parking lot private gun transactions, but don't know how it's typically done at shows. I'm asking because I'm thinking of going up to the Chehalis show tomorrow and have a few pistols I could bring to sell. The Portland show is much closer, but I'm afraid the choice S&W revolvers I'm interested in purchasing will already be picked over (plus the whole across-states thing). Anyway, do people (those who don't have a table) walk around with signs on their backs advertising what they have? Are these types of sales typically conducted inside the venue, or outside in the parking lot? Would I be allowed to carry a shoulder bag containing the handguns I'm selling?
