The Chilson Family of Tacoma, Washington, were in New Hampshire on a camping trip. The sons went out for a walk, and Calvin slipped and fell down an embankment, and became unconcious. His brother John headed back to camp to get help while the third brother, Troy, stayed with Calvin, and called for help. He was heard by Harry Wolfe, who was out fishing with Billie Wilson. Billie went and got help, and then transported Cal to Doyle Medical Complex.
