I went to a Gunrunners show in Lawrenceville a few weeks ago. It wasn't real big, but was set up good and everybody was very friendly! Some good deals, some regular (just like most shows). Hope this helps some....
Gunrunners are some good folk and they are usually a friendly show. You will see a lot of the same dealers though. *shrug* I use it for an excuse to go to Forest Park Army/Navy. =)
