You fly into one city or another, you do half an hour on local NPR, you do a few minutes on drive-time radio, you do an “event,” a talk or a reading or an onstage discussion. You sign books, you take questions from the audience. You go back to the hotel, order a club sandwich from room service, and leave a 5 A.M. call with the desk, so that in the morning you can go back to the airport and fly to the next city. During the week between September 11 and the Wednesday morning when I went to Kennedy to get on the plane, none of these commonplace aspects of publishing a book seemed promising or even appropriate things to be doing. But—like most of us who were in New York that week—I was in a kind of protective coma, sleepwalking through a schedule made when planning had still seemed possible. In fact I was protecting myself so successfully that I had no idea how raw we all were until that first night, in San Francisco, when I was handed a book onstage and asked to read a few marked lines from an essay about New York I had written in 1967.Later I remembered thinking: 1967, no problem, no land mines there.I put on my glasses.
