I've tried to wade through the many comments here, but will restrict my comments to my own experience at the recent meet...
This was probably the BEST York Meet I have attended to date. Didn't buy a single train item, but sure could have spent a good deal of $ if there was something I needed. Truth is, I already have more trains than I can make use of in several lifetimes--one of the advantages of having been in this hobby for a good number of years. But that sure didn't diminish my enjoyment of the meet one iota. I was fortunate enough to be able to meet-up with countless friends, some of whom I haven't seen in years, and several who I haven't seen for nearly a quarter of a century. That made this meet special for me in ways that are truly important.
I should note that even though I didn't buy any items this time around, I there was one item on my short mental list that I would like to have. In talking with Ken, from Trainworld, I found that he has it in stock at the store (it's a G gauge item, not O gauge) so I'll be calling Trainworld tomorrow and placing my order. So, technically, I guess it could be said that I did buy a train at this meet.
As others have noted, the hours of operation are clearly spelled out in the TCA Eastern Division's handbook, and they are in place so members who pretty much have to remain at with their tables in member halls also have a chance to visit the dealer halls if they care to.
And this fussing over older vs. younger hobbyists is ridiculous. There would be no York Meet if it wasn't for the older generations...even those older than me who are no longer with us. These are the people who, like me, worked their entire lives and were finally able to spend time and money on their hobby, be it trains or something else. They earned and supported the "perk" of having this meet in the first place, and even though the demographics of the hobby is changing, the seniors among us are still the foundation of the hobby because, first and foremost, trains, both real and model, were such an important part of our earlier lives. That is not the case for younger generations today, but there's little most of us can do about that aside from promoting the hobby as best we can. I doubt that it will ever again see the number of participants gleaned from those born and raised in the 30s, 40s, 50s, and 60s in particular, but that's just the result of societal evolution and inevitable change. The model railroading and train collecting hobby will still be around long after I'm gone, but we have to be realistic in our expectations in that regard.
Finally, my sincere thanks to the VOLUNTEERS of the Eastern Division who organize and conduct this meet. They can NEVER be all things to all people--TCA members or not--but they do one helluva job of putting on the world's largest and greatest toy train meet.
