Photo of the Day: A Saturday in Riverside Park, NYC

Nine days ago, on an afternoon visit to Columbia University and its surroundings, I stopped briefly to take photos by Riverside Park. I didn’t have time to explore its full four-mile stretch running from 72^nd to 158^th Street, but it was still more than adequate to convey a sense of the loveliness of this urban oasis—and, as you can see here, how many people see it as vital to their lives.
