I’ve done this on almost every continent (save Antarctica and Europe) and loved it every time. It’s amazing to feel like you are doing something that matters and to see the world in the process. I can’t think of a better way to travel.

If you are looking for some good programs, here are some friends and myself have looked into and/or traveled with:
i-to-i.com – short term, nonreligious, raise funds
Peace Corps – long term, paid for
Teen Mania Ministries – teenagers, religious, raise funds

There are tons of programs out there—so whatever you choose I can’t imagine anyone not loving their trip.

so go!
