Hi Horace, Glad you are interested i the swaps. They are at Oak Mt. State Park. There will be post started on Al/ Gardening Web. about where and when the swap will be. We list what plants or plant type items that we have to trade on our plant page, we also list what we are looking for. We check each traders plant page and jf we see something we want we email that trader and try to make a trade. We also bring plants to trade at the swap.
The swap usually starts at 10, we brake for lunch at about 12, then keep trading until.
We draw for plants after lunch. Each trader tryies to bring a plant or plant item to be given away at the drawing.
Catbird starts a post where our trader post what food hey are bring for our lunch. We have had some very good and interesting lunches.
I have been able to get all the plants that I have been looking for at the swap(except Touch me not seeds)

I hope this answers your questions. If not ask away.

Tony
