From a ForwardOnClimate.org Western MA Alliance press release:
Chartered buses and car loads of concerned citizens and students from western Massachusetts will travel to Washington, DC to join what is predicted to be the largest climate rally in US history on Sunday February 17, 2013. Sponsored by the Sierra Club, 350.org, and Hip Hop Caucus, the Forward on Climate rally at the National Mall will bring together thousands of voices around the country sounding the alarm of run-away global warming. The purpose of the rally is to urge President Obama to aggressively address climate change and to begin by stopping development of the Keystone XL Canadian tar sands pipeline.
