It's one thing to say you'll go on a big volunteer trip. But doing it? That seems much harder. Just ask Jimi and Cristi Cook. 

The Cooks are the co-founders and directors of Be the Change Volunteers, an organization that coordinates trips to impoverished countries around the world to build schools. It's the kind of volunteer effort the Cooks refer to as "the big one" – the kind that takes people out of their comfort zones.
