Ii like to look and what I do is take a quick run through to see if there is something I should grab before it gets too late. I then take a second slow walk through to look at anything small or I missed. I have bought a lot of gun parts this way for my old military rifles. I have seen boxes of mixed or miscellaneous stuff and found a hard to get part. Maybe a box of various old mixed magazines. I se it as that is why they named them Gun Show and not gun sales or gun buy. Used to see tables of display stuff only and peoples collections of military memorabilia and was for show and nothing for sale. Seems many shows have went the way of cheap china knife sales or selling some nonsense non gun related. Now I dont mind the jerky sales.
If we don't support the shows they'll go away and we'll have played right into the anti's wishes...they will have won without any further effort on their part. They will have accomplished a de facto gun show ban.
