Greg Mortenson's story begins with a failed attempt to climb the world's second highest mountain, and takes him on a mission to promote peace by building one school at a time. Mortenson chronicles his journey in his best-selling book, "Three Cups of Tea." Mortenson brought his message to a sold-out crowd at Washburn University last fall, where Washburn was participating in Mortenson's "Pennies for Peace" campaign to help raise money for schools and other projects around the world. KPR Presents Greg Mortenson, 8:00 Sunday evening.
