The Occupations began in earnest, at Wall Street last September and have been ongoing in many forms, some disrupted by police arrests and attacks. (Ignore the posted dates- that's just to keep this on view on the website).
OCCUPY TOGETHER, is an unofficial hub for the events springing up across the country in solidarity with Occupy Wall St. This site was created to provide people with information about events that are organizing, ongoing, and building across the U.S. as the 99%, take action against the greed and corruption of the 1%.

Locally, in the Bay Area, there several ongoing occupations taking place in Santa Cruz, San Jose, San Francisco, Redwood City, Stanford University, and Oakland.
