Here is a note from a friend who marched on 2/15/03 in NYC

L and I attended the march uptown today.  I will send photos as soon as they’re developed and scanned. Overall, I’d say the crowd represented a diverse range of ages if not interests.  From the signs and slogans, I gather most were emphatically but vaguely anti-war and anti-bush. A few specifically called for his impeachment, apparently on the grounds of Enron controversy. One or two posters boasted Quaker organization by-lines or authorship by other religious denominations. I did spot one Anarchist who gestured vulgarly to a cop and then ran away. Most strangely, although the density of the crowd surpassed NYC norms, people said “excuse me” and “pardon” when they stomped on your foot or shoved you out of the way. Very strange indeed.  Also, seemed to combine a large portion of non-New Yorkers. The police proved genuinely friendly although the poor horses were literally scared shitless. We did see one arrest. An inspiring uplifting display of democracy in action overall.
