First off, as has been stated several times, the York meet belongs to the Eastern Division of TCA. As in most organizations in America, you can get involved, get elected, get the membership behind you, and then start making the changes that you want. That may involve you moving into the Eastern boundaries.
Or better yet, build up the membership in your TCA division and get a show going that rivals York.
The comparisons between different shows would be more interesting if you kept the comparisons in the same hobby and in the same state. Compare other PA train shows to York.
I drive several hundred miles to go to York because of the concentration of dealers, diversity of trains, and fellow hobbyists. It's not perfect, but it is entertaining to me and worth the trip.
The huge group of volunteers and members of that division get a tip of the hat from me.
