The top photo is almost certainly my favourite from NYC5. It was a construction hoarding that Penny and I walked past several times, and the sidewalk was so wide that it had this central row of pillars and braces to support its span. The photo was taken very early on Sunday morning on Seventh Avenue.
The second photo is from the construction site that will eventually be home to the Whitney museum. It's at the southern end of the High Line park, way down in the Meatpacking District, and it can't have done well in the storm. It was taken early Sunday afternoon.
