Just got home from the show!
I was there from roughly noon until 1:30. My main objective was the O&WRHS sales table, which was plundered accordingly.
The place was packed while I was there, lots of families. Can't comments on sales, though I definitely saw people carrying purchases around.
After the show, I stopped by the Kingston Model Railroad Club, who were having an open house in conjunction with the show. What an awesome 2-rail O layout!!! It was a pleasure to walk around and talk with the guys. They have done a terrific job with it. If you ever get the chance, definitely go check it out.
A pic of my stash for the day... the three books that are stacked came from the Hudson River Maritime Mueseum right on the Rondout Creek, which I also visited during my time in Kingston.
