We have several gunshows a year, probably would be considered small by most standards.
5 bucks to get in, no charge for parking, about as cheap of entertainment as you could find anywhere.
I go for the entertainment, but don't pass up deals when I see one either. Usually around half of the tables are private sellers, the rest dealers and a few non gun dealers of one kind or other. I just walk by pretty much all the dealers, I do check out what a couple of custom knife makers have on hand.
It is the private guys that I check out the most, and generally find a deal at if one is to be had.
It is generally slow as far as castuing goes, as in pretty much non existant, some reloading equipment can be found at times.
