WWOOF

So, who has experience with a WWOOFer? I bumped into this on another Blog and am investigating. From what I read, it is a loose organization that hooks up volunteers who are interested in organic agriculture and self sufficientcy with farms willing to host them in exchange for labor. There's supposed to be some exchange of knowledge in there, also. I am not sure the model would work for us or not. It would seem a natural fit since we are working hard to develop a sustainable way of life and we already offer short term low detail housing. But the fact that part of our cash income is derived from that housing situation might make it mutually exclusive. If we were to trade some of that income generating housing for labor, it would put a crimp in our cash flow. But it's an interesting idea and worth hearing more about.

So has anybody else heard of this? Had experience with it?
