Prior to visiting a series of planned communities in and near Southern California's San Fernando Valley, I envisioned them as they were depicted in Greg Hise's book, Magnetic Los Angeles — suburban enclaves dotted with single-family homes, cars lining the wide curvilinear streets, children walking hurriedly to school. I almost expected my vision to blur slightly and force my surroundings to take on hues of white and black, matching the old photographs which told the story of the Valley's birth to a number of postwar self-contained suburban communities.
