Well, let's just see if we can't broaden your horizons a bit, NH:
On a wintry day in New York, huge crowds, prohibited by a court order from marching, rallied within sight of the United Nations amid heavy security. They raised banners of patriotism and dissent, sounded the hymns of a broad new antiwar movement and heard speakers denounce what they called President Bush's rush to war, while offering no sympathy for Iraq's dictator, Saddam Hussein.
"The World Says No to War," proclaimed a huge banner over a stage on First Avenue near 51st Street, the focal point of crowds that filled the avenue from 49th Street to 72nd Street and spilled over into side streets and to Second, Third and Lexington Avenues, where thousands more were halted at police barricades, far from the sights and sounds of the demonstration.
Crowd estimates are often little more than politically tinged guesses. The police commissioner, Raymond W. Kelly, put the crowd at about 100,000, while the organizers said 400,000 people attended. Given the sea of faces extending more than a mile up First Avenue and the ancillary crowds that were prevented from joining them, it seemed that something in between was probable.
