A father just emailed me this about his son's experience: "He spoke so positively about the sites you visited and what he learned. But he also gushed about not losing anything, keeping himself organized, getting into a routine with his housing mates, following the itinerary, and exploring with a sense of commitment to personal responsibility and the respect of others in the group." People often fail to account for the learning that takes place on that level through an experience of this kind.
