Greenpeace

Hi Everyone, My name is Cassondra and I was just wondering if I could get your guys' help?  I live in Berkeley, California, and I really want to get invovled with protesting and actually start a protest of my own...but I have no idea who would do that, and I know no one in Berkeley whos like that.  It sounds crazy, I know, but how can I go from shy girl to peace-loving protestor?  I need advice!
