It was a chilly, raw, Sunday morning. The temperature was in the low 50s and the wind was brisk and cutting as I decided to walk up 7th Avenue from its beginnings as West Broadway, just north of the World Trade Center. The day started with brilliant sunshine before quickly clouding over and turning grey before I even reached Hudson Square. The day ended with a quick excursion into the newly opened 34th Street station on the 7-Line.
