If you like these things:
-manual labor in exchange for garden produce
Then you might want to check out this: http://www.wwoof.org/index.asp. It's simple--you volunteer in exchange for food, accommodations, and organic farming experience. I've been a member of the USA chapter for a couple of years and am hoping to make some long weekend trips to local farms this summer. I think it's such a great way to learn basics and gain confidence in starting your own garden (however small it may be). It's so valuable to be part of this kind of community. There are opportunities year-round, but late spring/summer/early fall is generally the best time to get involved...so I wanted to throw out the info right now.
