The Great Blackout Of 2003
"At approximately 4:20 PM EST on August 14, 2003 the power went out in New York City. Soon it was known that it was not just in Manhattan but in much of the northeastern United States, affecting an estimated population of 50 million people. The photos below were taken during my walk home from downtown Manhattan to the Park Slope district of Brooklyn, approximately 3.5 miles."
