Members of the Occupy Maine movement are celebrating the one-year anniversary of the national Occupy movement. Occupy Maine members and supporters rallied in Portland’s Monument Square on Monday afternoon. A picnic and birthday party was planned Monday evening at Congress Square. The events took place as Occupy Wall Street protesters in New York celebrated the movement’s anniversary by clogging intersections in the city’s financial district and marching to the beat of drums. Occupy Maine organizer Rob Korobkin said the Maine group has been working with people whose homes are being foreclosed upon, while also working to ensure that Congress Square remains open to the public rather than being taken over by a hotel. Occupy Maine members camped out in Portland’s Lincoln Park from early October last year until February.
