I wish they provided a vendor list for their shows.
Same here. My brother and I just got back a little bit ago. A few I know of that are there are B&B Hobby out of Bridgeville, PA, M& H Hobbies from Palmyra, New York, Route 30 Hobbies out of New Jersey, and this one guy Scott Schaller is selling HO and N scale steel mill stuff. There are a bunch of other vendors but I didn't get their names. I also liked the Allegheny Northern Railroad Club's HO layout and TrainTrak's N scale layout.
