A group of Occupy Wall Street protesters coordinated a march in mid-town Manhattan today, delivering 6,000 “angry letters” to five major banks.

Before the march, the group, Occupy the Board Room,  invited people to submit letters online to Bank of America, Morgan Stanley, Wells Fargo, Citigroup and JP Morgan Chase.

Today, the group delivered printed letters to the doors of the bank headquarters.

The protest was mostly lighthearted, as some dressed as pirate-bankers and chanted rhymes like, “Greedy banks, rich and rude, we don’t like your attitude.”

In front of the Bank of America headquarters and a line of security guards, dozens of protesters folded the letters into paper airplanes, then voluntarily picked them up.

In front of the Morgan Stanley headquarters, protesters prepared a singing telegram with the words, “I live pay check to pay check and find it hard to pay rent. I am not writing to offend or attack. I simply want to share my struggles.”

Protesters asked bank spokesmen to invite the CEO James Gorman to lunch.

After declining, the spokesmen agreed to pass along to Gorman the contact information of a protest leader, Austin Guest.

Guest, who co-founded OccupyTheBoardRoom.org, said the spokesmen were “nice,” shook their hands, and thanked them for their time.

Earlier, just as the weather in New York City has dropped to unseasonably low temperatures for the Occupy Wall Street protesters, the Fire Department of New York (FDNY) announced that it removed six generators and 13 fuel containers during a coordinated inspection this morning in Zuccotti Park.

The FDNY released a statement about the inspection in the park known to the protesters as Liberty Square, where they have camped since Sept. 17. The occupants were “cooperative” during the 30 minute inspection, the fire department said.

“This action was taken to address the dangerous conditions posed by the presence and/or use of flammable and combustible liquids and portable generators in a public space, which is prohibited under New York City law,” the statement said.

The weather in New York City is expected to drop to the low 30s this weekend, with possible rain, wind and snow.

But the Fire Department said no one will be permitted to bring portable generators or flammable liquids into the park, and it will continue to monitor conditions at the park “to ensure public safety is maintained with regard to fire and life safety.”
