A bunch of students, the unemployed, union members, etc., are camping out smack in the middle of the New York financial district. 24-7, 7 days a week, and it's been going on for a couple weeks now. It's a protest against political and corporate corruption, banks getting big bailouts while ordinary people lose their homes from foreclosure, see their jobs get outsourced, and pay a higher tax bracket than rich investors who know all the loopholes.
Funnily enough, it's getting almost no coverage from major media outlets. You have to follow blogs and twitter and Anonymous' websites.
