Protesters affiliated with the Occupy Wall Street movement march across the Burnside Bridge as part of several activities planned today in Portland, Ore., Saturday, Oct. 29, 2011. Having started in New York, Occupy Wall Streets demonstrations now take place all across the United States, as protesters speak out against corporate greed and the gap between the rich and the poor.

PORTLAND, Ore. — Dozens of Occupy Portland protesters took their demonstration against income inequality and what they call corporate greed to the city's ritzy Pearl District on Saturday.

Demonstrators marched through downtown, across the Willamette River and back. Some of them carried sleeping bags and said they planned to camp out in the park near expensive condominiums and high-rise office buildings, but authorities say they would not allow it.

Authorities say demonstrators must leave the square before a midnight curfew takes effect.

Some demonstrators have said they want to camp out in the Pearl District because they view its residents as part of the wealthy demographic they're protesting. Others said they're simply looking for more room because the movement has outgrown the two downtown parks it already occupies.
