I came to San Francisco in 1982 to take care of sick babies at University of California Medical Center Hospital.  (This was several years before I started writing for a living.)  Prospective students compete strenuously to get into UCSF, one of the best medical schools in the nation.  The place is huge.  Here is the back side, shot on my afternoon walk yesterday. Careful observers will discover fog softening the buildings to the back, a sure sign that the summer weather pattern is settling in.
