Tensions rose again in Zuccotti Park Wednesday between Occupy Wall Street protesters and police.
At least two demonstrators have been arrested for disorderly conduct and trespassing.
More than 100 protesters re-occupied the park.
About 60 of them marched 99 miles from Philadelphia, symbolizing the plight of the so-called 99 percent.
Returning to the park was a reunion of sorts.
Occupiers said they want people to know they're still around and so are the economic problems.
"Standing in solidarity with Occupy Wall Street takes a stand against all the corporate bankers messing up the whole country," said one.
"I'd like to be able to actually walk from Philadelphia to New York and bring issues to people, have them ask me a question and that was I can actually give them an honest answer," said another.
Protesters stayed in the park for about two months in the fall before Mayor Bloomberg ordered them to be evicted.
