Summer did not just end, it fled, tearing away in a flash from a week’s onslaught of cold, dark rain. We huddle indoors, pull out winter sweaters and heavier blankets. So I dig deep into my cache of pictures for some light. I remember a bold, brisk San Francisco summer’s day. The fog burned off, the sun lit up all the buildings around Union Square, and glass melted into glass images until it felt like a fairy land, a veritable universe of stars and gold and glints of light. Nothing like summer in San Francisco.
