Two days later: I wanted to go to the lunch, but I actually got a ride to the show and so was under the constraints of doing what my driver wanted. I got there about 10:30am and left about 1:30.
I did buy a very nice Williams 4-6-4 Hudson Streamliner #4001. If I hadn't had a ride, it would have been a Real Pain to get it home. Because it didn't run in reverse, no one wanted it. But because I just display the trains (no layout), it was ideal for me.
