When I lived in the Triangle, I went to this show ever time it was in town. It is in the Kerr Scott building at the State Fairgrounds and is smaller than any other Raleigh show, but there is more concentrated good stuff than with the regular gun shows. I used to set up there with a friend of mine and we had a grand time trading with other collectors who set up. As a general rule, you will see more collectors set up there than gun dealers. Collectors of all kinds - guns, uniforms, edged weapons, badges, militaria, etc. However, as with other shows, the quality of it has declined over the years. Some of the old collectors I used to trade with have died or are in too poor health to continue. Still, it is worth attending. I won't be going this year, but I attended last year and had a good time.
One guy I knew always hit the flea market Saturday morning before the show and would come in laden with WWI military stuff. If you make the trip, come early and hit the flea market, too.
