This morning I walked from Fiftieth Street down to Sixth Avenue and Spring. The city felt as though it were recovering from a devastating hangover. I needed to move, needed to feel the air in my lungs as well as the blood pumping from my heart and through my veins. I walked by B&H (VIDEO - CAMERA - AUDIO) at 34th and 9th. Just before crossing 34th I looked west, where 34th Street drops down toward the Hudson; and in the distance and amongst the fog and clouds of the morning, the end of the street looked like the end of the world.
