I'm sorry, but all I can think about when I see "Gun SHow" with the quotes is that you went to Gold's Gym during peak bodybuilder hours.
I go to a fair number, either getting in free with my .mil ID, or as a vendor (I provide security and a quick salesman's tongue for the larger vendors by request) and I've seen both. Most of the shows I go to are the Dixie Gun and Knife shows in the Southeast. Some are great, some are lots of milsurp and cowboy guns, and some are mostly saturday night specials and Hi-Points with paintings of wolves.
Did I mention what I do at slow shows when I'm a vendor? Play count the wolves. One wolf on a t-shirt is one point, two wolves is two points, etc. Repeat offenders on the same day to not count. First guy to reach 50 confirmed points owes the other guy a soda, at which point you reset and start over. If I could drink at gunshows, I'd make it a drinking game with a camlebak full of vodka and be SLOSHED by noon.
Playing without alcohol, I've gotten two free sodas and bought one for another guy, all in one day.
In other gunshow news, I have taken to wearing ZS t-shirts, and carrying a stack of the business cards. One or twice, I have had someone hand the card back and say "thanks, but I know. I donated to the [disaster drive] and my membership is pending." I went to a show back in December and was telling someone about ZS, when someone standing nearby goes "Yeah, the organization's done some great things. You should check them out." I still have no idea who he was.
