Even though I paid a couple of years ago, I forgot to pick a table till the last minute and got one top level, not main floor and still had folks coming by the whole time till I mostly sold out at around 2:00 and packed up. I just brought odds and ends and sold $1200 worth of stuff I just needed gone. If I had known how much room I would have I would have brought twice as much stuff.
The thing that made it more like the gun shows from 30 years ago is a good majority of the folks coming in the door brought in guns and accessories to sell or trade. I saw a ton of great deals. Buyers and sellers were happy. I didn't see a bunch of the "negotiating" normally seen at gun shows. People put a fair price on the stuff, buyers recognized a fair deal and paid cash.
It wasn't the same old vendors that fill the guns shows, it was just a bunch of folks who cleaned out their stuff and had a big gun loony version of a garage sale.
I bought a nice redfield / leupod version 3x9 for $75, a vintage folding Normark filet knife for $10, some Weaver grand slam rings for $10, a gunsmithing screw driver set for $5, and a threaded barrel Norinco JW-15 .22 with a scope for $75.
