There were long lines and crowds at the gun show, according to the Statesman.
(Before today, I’ve never had to wait in line to get into a gun show, except maybe the one time I went with Borepatch and we had to wait for the doors to open. It took me about 40 minutes in line to get into the show; I got there around 10:30 AM. Two friends of mine got there later and reported the wait was much the same, even at 1 PM.)
Edited to add: Lawrence was there as well; here’s his report.
