This signal tower was tucked in the shadow of a freeway overpass on the San Francisco Peninsula. A woman was on duty in the tower when I painted on location one late afternoon in 1973. Youngsters coming home from school were walking the rails and indulging in pushing and shoving antics like kids will do. Suddenly, the window sash in the tower flew open, and she yelled, "You kids get outta here!" They scattered quickly. The tower burned down in a fire of unknown origin several years later.
