There's usually been some kind of line, but the last time I went was right around the '08 election, the first time (in this series) that people went crazy. Yes, the wait was considerably longer during a "panic" phase.
I had to park way far away, take a shuttle to the expo, stand in line, let the guards at the door inspect my pistol (and zip tie it), then enter the show via the rear entrance.
I've since decided to do my shopping off the net. Gunbroker mostly. So far.
