Hands down, that was the worst gun show line I've ever seen. I've been going to the Market Hall Show for over 25 years, and that line was 2-3 times longer than I've ever witnessed (I didn't make it to the Thanksgiving post-Obama show, though). It zig-zagged all the way back to the parking garage. We left a little after noon, and there was still a line half-way out into the parking lot!!
As for deals, the pistol prices all seemed at least 5-10% higher than they were back in the summer. The AK/AR prices were ridiculous. Del-Ton's and Olympic Arms AR's were going for $1100-$1200. The average price on a WASR AK was $625-$650!! Colt AR's started in the $1600-$1700 range. Saiga's (223/308) were pushing $450. I did see some CZ VZ58's for $859. I tried to get a mil-spec buffer tube for an AR from Model-1, but balked at the $45 price. I saw no real shortage of AR mags/parts/guns, merely a shortage of reasonable prices. Everybody thinks they're sitting on a gold mine!
The dealers were getting pretty savvy. With so much traffic, they didn't seem to have bargain prices on anything. I guess they figured that if you didn't buy it, there'd be at least a few thousand more people come along after you......
