If there was a thread on yesterday's (3/22/15) train show in Kingston, NY, I missed it.
Regardless, I went to the show. The tables were sold out. They had several display layouts. and face painting. The facility they use has a small play room with couches. There was a TV in the corner with Thomas the Tank engine videos playing, and lots of wooden trains for kids to use. I think there was lots of legos as well.
Decent food with prices that weren't bad for that sort of event.
The show was well attended with lots of families with children.
Well done!
