Anti-Wall Street demonstrators said on Saturday they are growing out of their lower Manhattan encampment and are exploring options to expand to other public spaces in New York City.

Protesters complaining about what they view as corporate greed have been camped out near Wall Street in Zuccotti Park for three weeks, staging rallies and marches that have mostly proceeded peacefully but have also resulted in confrontations with police.

On Saturday, several hundred protesters marched north to Washington Square Park — the site of protests against the Vietnam War in the 1960s and 1970s — to discuss expanding their encampment to other sites…

On Friday, Mayor Michael Bloomberg said the protests “aren’t productive” and bad for tourism, even as he said he was sympathetic to some of their complaints.
