I've been to the show about ten times (including today). Some of the same guns are on the tables that were there 5 years ago. Not quite sure how they can hang onto inventory forever. I'd say the biggest thing still is the black guns and loads of ammo (for the black guns).
I go to the show about once a year. Renew my NRA membership and get in free. Seems like a decent deal all around.
PS. At least I got to swap some stories with eightbore and talk about a certain 28 gauge CHE parker on a nearby table.
