New York: Occupy Wall Street is going on the road, a two-week walk to Washington. A small group of activists plans to leave Manhattan's Zuccotti Park at noon on Wednesday and arrive by the November 23 deadline for a congressional committee to decide whether to keep President Barack Obama's extension of tax cuts enacted during the presidency of George W Bush.

Protesters say the cuts benefit only rich Americans.

The announcement came the same day that David Crosby and Graham Nash of Crosby, Stills, Nash & Young, planned an acoustic performance in the park for supports and passers-by.    

Kelley Brannon is organising the 380-kilometre march from New York through New Jersey, Pennsylvania, Delaware and Maryland with a core group of a dozen activists, picking up other marchers along the way, even if for a day, or only an hour, they say.

"Occupy the Highway," as it's been dubbed, will start from the Manhattan park where the first Occupy encampment was set up, with a ferry ride across the Hudson River from West 34th Street to Elizabeth, New Jersey.

Brannon likened the effort to the long-distance marches led by the Rev Martin Luther King Jr during the civil rights era.
