Even discussions of architectural esthetics have taken a strange turn. The Bloomberg Tower is now finished, dominating the skyline in one area of midtown Manhattan; love it or hate it, it" s quite a building. "I just wish it wasn" t so tall" , someone lamented at dinner. The citizens of New York, who live in the spiritual home of the skyscraper, now fear the office tower and the high-rise. In San Francisco they build structures that are earth-quakeproof. But there" s no structural steel, no reinforced foundation, that can ward off fear. It" s been nearly five years since all area in the southernmost part of Manhattan was renamed Ground Zero. On September 11, 2001, New York became a city of survivors; That" s on a sliding scale, of course: it would be all insult to claim otherwise.
