I've also bought and sold a couple guns via crocodile shows, but both cases were flukes. I just happened to be driving by when I ended up with my colt accurized. The sale of my cz75b happened there, because the guy who wanted it wasn't sure my asking price was reasonable. 20 mins at the show he comes running up begging for the transaction. lol They didn't have **** that weekend.
When I was younger, they seemed to be better (Twin Cities shows). The last one was so weak (it was at St Cloud Armory), I pretty much wrote them off.
I spent my wad on my AR, so going wouldn't do me any good till I get a couple checks I'm waiting on (should be here early next week). The military show sounds a lot more fun. I'm torn between trying to get my wife to come with me and kiddo, or going alone so I can actually buy stuff.
