It was a day of infamy followed by tremendous grief: The Sept. 11 terror attacks left New Yorkers shaken and heartbroken in its aftermath. But that didn't stop locals from turning out in droves to pay tribute to the nearly 3,000 people who lost their lives in the Twin Towers and at the Pentagon.
Vigils were held across the city, and memorials popped up around New York, from Manhattan to Brooklyn to Staten Island.
