October 30, 2012, 3:31 pm: In the relatively elevated neighborhood of the Upper West Side, downed trees line most of the streets. Near the Time Warner Center, a bus signpost, which had snapped at its base during the worst of Hurricane Sandy, lays on the pavement. There is debris, but compared to other neighborhoods, not devastation. And unusually, business is as brisk as a holiday shopping weekend. Grocery stores such as Zabars, Fairway, and the West Side Market are currently abuzz with activity, and there are long waits at local restaurants.
