Paul Newman's idea in the 1980s to start a camp in Connecticut for critically ill children has grown into an international phenomenon with a ninth "Hole in the Wall" camp opening soon. The camps will host thousands of children, for free, well after the 81-year-old actor speaks his last line before a camera.

"If I leave a legacy, it will be the camps," Newman says.

At the Double H camp, campers climb ropes among tall trees, paint faces, ride horses, swim and play soccer. Campers' diagnoses range from cancer to muscular dystrophy.

Double H (stands for health and happiness) opened in 1993 after the late amusement park developer Charles Wood proposed to Newman that they convert an old dude ranch into a second Hole in the Wall camp.
