Has anyone ever been in or known anyone in the Peace Corps?

I’ll be graduating college in a year, with a degree in Theater and Environmental Studies, and I’m considering joining the Peace Corps. It seems like an incredible opportunity to travel, learn another language (probably French since I studied it for all four years of high school) and learn organic, sustainable agriculture techniques. Food security is an incredibly important issue in the World, and particularly in the Third World, and being able to make a tangible difference in people’s lives on a level as fundamental as food seems like it would be a life-changing experience. I’m a little worried since I don’t have any real experience with agriculture, just a desire to learn. Does anyone think this would be a problem? Should I do something else (like WWOOF) to get more experience?

If anyone has any stories, first or second hand, about the Peace Corps, I’d love to hear them.
