There was a post with a simple title, like "Train Show" or something simple and generic like that. Didn't get many replies.
I went on Sunday afternoon - it was surprisingly crowded (don't know if people were buying or not, though). Parking was tough, since they had a computer show going on in the other half of the building.
I didn't buy anything this time, but had a good time with rest of the Pittsburgh Independent Hi-Railers, and spent a lot of time chatting with old friends and new ones.
