Returning to Manhattan from upstate New York, we snapped this shot from a Hudson River Line train looking west over 125th Street. The thoroughfare is the main cross-town artery running through Harlem. It was a cool and quiet Sunday of a long holiday weekend, but that didn’t stop the ad hoc sidewalk flea market from massing on the south side of the street. (You can see a few vendors with their blankets laid out on the path in the lower-left of the image.)
