Into the night, they pounded away at Zuccotti Park, a drum circle that is the soundtrack to the Occupy Wall Street protest, a protest that has plans to make even more noise.
"We're planning to take Wall Street," a protester said.
On Thursday, what they are describing as the two-month anniversary of the Occupy Wall Street movement, protesters are planning to put so many people in Lower Manhattan that they delay the opening bell and disrupt the business of the New York Stock Exchange.
Just as police in other cities are starting to remove the Occupy protesters from public and private spaces, as crime and violence rise in and around those spaces, Occupy Wall Street says they're not worried about Mayor Bloomberg taking similar steps.
Still, not everyone thinks the movement can shut down the Stock Exchange.
Mayor Michael Bloomberg says demonstrators won't disrupt Wall Street, that the Stock Exchange will open on time and people will be able to get to work.
At 3 p.m. Thursday, demonstrators are planning to get on city trains in all the boroughs and proclaim their messages to the riders.
Then a 5 p.m. rally is planned for Foley Square near City Hall. Afterward, there's expected to be a march to area bridges.
