Rachel's Challenge

Just got back from the Farmington High School where I attended a presentation by Larry Scott of Rachel's Challenge. Great program, great message, great cause. Very moving story. What is Rachel's Challenge? As described by their web site:

Rachel Scott was the first person killed at Columbine High School on April 20, 1999. Her acts of kindness and compassion coupled with the contents of her six diaries have become the foundation for one of the most life-changing school programs in America.
