I made it to the Wyndham this afternoon (thanks Peter for letting us know it was going on).
There are lots of trains out there in the world to be had still. Not much modern stuff, though I got a modern MTH tank car and modern Kline vat car that caught my eye. Also Anton (one of the first tables on the right) hooked me up with some super trees kits to add to my structure building plans.
Saw Kenner Star wars items here for the first time - a couple Falcons and an At-At if you are in the market 
Also lots of just stuff like Peter stated. Not so much strictly O scale anymore. HO, Flyer, model kits, random toys. I wonder if any of that non O scale or Flyer stuff sells at these meets.
People seemed to be packing up and unpacking at 2:30 which is perplexing.
Also one booth had several foam sections of scenic mountains with trees that looked cool but I did not investigate further.
Beautiful 72 degree sunny weather also.
I hope you all have a great York weekend and find what you're looking for!
