Greenberg and other local shows in the area are reasonably well attended, so if 20-30% of those folks make the trip to York it would seem to be a worthwhile effort. Whether the same number of folks can be turned into dues-paying members is another matter...it would seem doubtful.
Maybe I was travelling in a bubble, but it seemed that this York was pretty crowded. I had to drive around for a bit Friday AM to find a parking spot...first time that's happened in a loooong while.
