Been to a whole lot of them. When you enter, that whole main room is basically the exact same people that are at every show, a lot of dealers and a lot of novelty items in that first room. The side room up and to the leftalso has a lot of people you see at every show, but it is where you will also find the private vendors who just rent a table for the one show.
Anyways, you won't find any good deals on ammo unless it is from a private seller. There are some good deals on firearms to be had, but many of the vendors are not much better than what you will find in the local stores.
It is still always fun, and definitly worth the couple bucks it costs just to walk around for a couple of hours.
And keep an eye on the crowd as well as the tables, anyone can bring anything in and just sell it while they walk around. (I will be on Saturday )
