While in New York we had perfect walking weather. We must have walked every block of Manhattan. We visited the WTC site, the memorial is not finished. We also went to the top of the Empire State Building (yes we were tourists). We paid extra for Express Tickets. An Express Ticket means no waiting in line. We got to the top in less than 10 minutes instead of an hour and 45 minutes. Well worth it. The Empire State Building may be old and its height has been eclipsed by many other buildings but it is a Grand Dame!
