Two points to make. The picnic_also_a_fragswap has been discussed several times, but has been voted down because the event is designed as a club family event where the club springs for food and such. We don't fancy feeding 300 people that show up to swap corals or worse having to police who is there for what purpose.
As for the last Pittsburgh swap, it was well organized by the club with several vendors and many people SAYING they were coming and bringing frags. And then 4 people showed up. It was a ton of effort with no gain at all. Since then just about every year a handful of club folks will speak up about having a fragswap and are told "feel free to organize it and tell the club how we can support the effort" and that is as far as it goes. There is a very big difference between wanting the club to organize a frag swap [for you] and stepping up to organize one [yourselves].
As always, if any of the club members want to organize something like this they need only speak with the board to tell us what you need from us. As long as your planning is more than "how about you set up a fragswap" we'll be happy to assist.
