Well I went this morning. As others said there was ALOT of old military rifles(not really my niche, so I can't even really say what I saw), also alot of WW2, Nazi/Jap collectibles.
I really feared this would be a waste of time, but to my surprise. There was a decent amount of modern guns, a bunch of ARs, and AR parts. One table was filled with Magpul-handguards, magazines, etc. I saw one Saiga 223. Lots of modern shotguns. I didn't find any deals on ammo.
I picked up a Hi-point 9mm carbine, 2-50cal. ammo cans, and a knockoff grip-pod. Overall, for my first gun show it was a pretty good time, and I can't wait to go to one of the 'good' gun shows.
