I think we have been pretty clear about our intent for the get together... there are multiple posts on the topic. It is not a card show. It is a day for prewar (mainly) baseball collectors to hang out, show collections, discuss cards, make connections, eat, drink, and, if a deal develops, buy/sell/trade. It is a very laid back atmosphere, but there were definitely some sales and trades that took place last year, and that is fine. Just don't think of it as dealers on one side of the table and buyers on the other side.
There will be some space limitations, so for those who want to set up, plan on no more space than about the area that two showcases would cover. Space is first come, first served, and please monitor/safeguard your cards at all times. All of the following are ok:
-Displaying your cards in showcases (2 max)
-Bringing cards and laying them out on a table
-Bringing cards in a carry case/storage box and just walking around with them
-Coming just to look at other people's collections (although we would encourage you to bring something that you collect)
I think those who have attended before (and commented above) have been accurate in their descriptions of the feel of the event. If anyone wants to see what it looked like last year, here is a link to a video I posted on my YouTube channel:
