WWOOF = World Wide Opportunities on Organic Farm -so awesome! You can work on organic farms around the world in exchange for rooms, food and the opportunity to learn about how an organic farm works. The WWOOF was started in the UK back in 1971 and now it's world wide.
I think this sounds like an awesome idea and would be great to travel from country to country, all while learning a little bit about how each country handles organic farming. Go HERE for more info!!
