Excerpt: "In early December, the San Bernadino hillside was ravaged by a fast-moving brush fire which destroyed more than 200 homes and damaged many more. Later that month, however, a fire of another sort came ablaze on the hillside. It was the spiritual fire of nearly 500 young Friends from 11 yearly meetings who converged upon the Campus Crusade Headquarters at Arrowhead Springs, from December 26 to January 1, for the second gathering called ''Youthquake."
