I can't answer your question of is it any good, but I will be going Satureday morning. The FIL goes to this one frequently. He has come home with a few guns from there over the years.
It's probably comparable to any of the other local gun shows.
It will take you a couple of hours to see everything.
Of course, being right here in Bedford, I will be going.
You said everything I was going to say. If you are local then hit it up. Never know what you can find. If I get really bored I may go up that way this weekend.
I'll probably get off my duff and head down that way this morning. I don't anticipate anything great, but you never know. I'll probably take one of the guns I'm willing to part with to see if there's a deal or trade to be made.
