Well I am emotionally torn when people complain about a gun show. Because so often so much depends on the luck of the draw. What the dealers have, what the walk in have. Also what you are looking for and when you are there.
I have honest to God been at a show that was a bust just to find out and hour after I left some one brought in a bunch of things I would have wanted.
Also you hear people complain that there was nothing at the show and they came in the last hour of the last day of the show when everything has been picked over. (Of course that has its own pluses)
Also many time we reviewers of gun shows so not do a good job.. Someone will say, "this show was bad", and leave it at that.. Which may or may not be true.. As gun show commenter one really need to state what kind of items you were looking for and why it was bad Where as no one likes to tip their hands what they are wanting.. But some idea would be nice...
I E. If someone came from a show and said it stank the big one.. It would be nice to know that they were there looking for parts for their AR platform and all they had was older guns and ammo.. Because that way people looking for older guns and ammo would be able to use that info. LIke wise someone looking for S&W revolvers saying a show stank because of all the AR parts there would be more helpful then just a negative comment.
Trouble with gun shows, to many different people who shoot and things to shoot. Personally you know you are at a good show if there is at least one belt fed.
We the gun show attendee do a disservice to those who set up at those shows and promote those shows with such blanket negative comments. That then can cycle against the attendees because the next show may have fewer dealers and walk ins.
