I used to drive all over attending gun shows, now I primarily just go to the Oaks, Pa show. Yes, the admission fee is getting high, there are few deals to be found, and the selection of old guns ain't what it used to be. However I primarily go because I enjoy the trip. Several current and former co-workers go to the show with me, so we get to hang out, look at guns, watch the kaleidoscope of humanity at the show, and stop on the way home for a good dinner. I usually run into a bunch of guys from my club, and a bunch of my Dad's old co-workers. It's also a chance to see what neat old S&W's Jeff from Highland Arm's might have.
I started attending gun shows in high school, going with friends from school and my Dad. The first gun show I went to was in Downingtown, Pa at the old Mickey Rooney Tabas Hotel. Lot's of different shows have come and gone over the years, and in general the shows aren't as good as they were in the 90's. In all those shows I think I've only bought guns from maybe five dealers, but I bought a bunch from those dealers over the years. Deals still turn up if you look carefully and are lucky.
