Carl Nolte has spent 60 years at the San Francisco Chronicle. A fourth-generation San Franciscan, Nolte has seen it all, and still, he says, he feels a sense of surprise on every block. The current crises, however, have made him long for a city he may never see again. As he says, he knows what’s going on all over the world, but suddenly he’s not sure what’s happening nearby in Chinatown or the Mission or Noe Valley.
