When you think of teenagers on spring break, visions of Daytona Beach or Cancun may come to mind — not necessarily a trip to Cambodia.
But that's where Kate McNamara, a 16-year-old New Yorker, went on vacation with her family, volunteering to teach children English and build wheelchairs for land mine victims.
"It wasn't that long and it was a small group of people … but it made just such a huge difference, " she says. "It was one of the most rewarding things that I think that I've ever done."
Her mother, Elizabeth McNamara adds, "In a world that needs so much, just to a little bit to make a difference in someone's life is a very positive experience."
