I debated on whether or not to comment on this thread but I’ll share my thoughts.
As someone on the younger side of this hobby I’ll say this, York is an incredible experience and I believe it’s critical to the future. That said, the current format doesn’t work for those that represent the future. Thursday is the best day to find that rare item and get the best product before it’s gone. But the future of the hobby is working or in school. The half day Thursday isn’t really enough to soak it all in, so you must go 2 days. That’s now 4 vacation days a year we have to take (figure 20% of most people’s allotted vacation time) to attend York 2x a year. Especially for those of us with children and hectic lives, it becomes a barrier to attendance.
Going to a Friday & Saturday show seems like it makes the most sense to me. Friday members only and Saturday open to the public.
