Seems to be going well.
6:38p.m. ET: ABC News' Gregory J. Krieg reports: The march has passed through a narrow corridor along Park Row and back south down Broadway from Foley Square, returning to Zuccotti Park. We've heard reports on crowd size ranging from 2,000 (an officer guessed) and 15,000 (organizers guessed). I'd say it's much closer to the latter. And for every protester, there must be two metal barriers. This is a very tightly-held rage.
