On the hills that rose across the valley from my house, a giant C was emblazoned on the hillside. Most of the time, the c was set off by brown grasses, but sometimes, in the springtime, it gleamed from a sea of green grass dotted with herds of grazing sheep. The C stood for Capistrano, and it had been put there by some high school kids from Capistrano Valley High School in the 1960s. Until my father told me the story of how it got there, I thought it stood for Christa.
