^^ Malawi, huh? I'm saving up to do one in either Bali or, preferably, India next year or the one after. Did you enjoy the experience?
Loved it, best thing I've ever done. We worked in schools and went on safari and met lots of brilliant people. You're right though, it does take a lot of saving up- my trip took me 18 months of fundraising, but it was totally worth it!
