Myself and the Mrs went once a couple of years ago. I sold two guns (Beretta 40 Cal & a Bersa 380 Plus) purchased one (S&W 442) and walked out with a little over $400 in my pocket. I would call that a good day at the show.
It was a great time, but kind of a cattle call. I just wish it was held in a larger space. I must say though that the crop dusting was quite overwhelming a couple of times...
At the time, I wasn't part of INGO so I didn't stop at the booth, but if we go again that will be an added bonus. Took some of the money we made and stopped at Santorini's in Fountain Square on the way home. Made for a nice day.
