Here is where we can chat about seeds we have, seeds we're looking for, etc. You can also arrange trades on this thread (or via D-mail).
It is not necessary to arrange a single trade in advance for the swap, but it can be useful. Swap discussions are also handy for gauging interest in a particular kind of seed, so when you're packaging seeds you know if you should make up 6 packets or 26.
As I've done in the past, I'll put together a tray of "goodie bags" with names on them. This makes it really easy for you to earmark seeds for a particular person and just drop them into that person's bag when you arrive. Nametags will be near the goodie bags -- please use them! I'll also have seed baggies, label slips, and pencils for any last-minute dividing and sharing, but you'll want to do as much labeling in advance as possible so that doesn't cut into your swapping & chatting time.
Let's post our "have" and "want" lists on a separate thread here: http://davesgarden.com/community/forums/t/1294097/ If we make just one post per person on another thread, our lists will be easy to find. Sometimes these trading/discussion threads get pretty busy!
