I go to shows fairly often. Sometimes I find good deals, sometimes not. Sometimes I even see/find hard to find guns that interest me (at last months show I saw not one but THREE S&W M52s, which are on my bucket list), other times nothing but new guns and junk.
No matter, something always follows me home. Parts, accessories, brass, SOMETHING. Plus, the venue has really, REALLY good hot dogs, lol.
Either way, it's a fine way to waste a Saturday. $6 is little to pay to be around like minded people and amongst things I enjoy. Sometimes I'll spend an hour or more just shooting the bull with someone there, usually an old timer, and it's always entertaining and usually educational.
I've done it all my life, I guess it's just my thing.
