Wwoof - Organic farm volunteer program

I kept seeing references to this, but dismissed the links initially. Now I'm intrigued. This might be an enlightening and rewarding way to travel and meet new people. The physical labor would be good for my mind and body, while also connecting me with nature and grounding me in the natural food cycle. The more I read about it, the  more I'm interested!

The details:

"Visitors, or ‘WWOOFers’, spend about half a day on a host farm, learn about the organic movement and sustainable agriculture, and receive room and board - with no money exchanged between hosts and WWOOFers. WWOOF is an educational and cultural exchange program. WWOOFing is a way to learn practical farming skills, be part of the organic agriculture movement, and experience the heart of American agrarian culture."
