Living in a big city can be daunting sometimes. Walking home alone down dark streets or unknown neighborhoods can be a bit intimidating. We’ve all been there before. Enter Hollaback! Boston, an international non profit who has literally taken the conversation to the streets, is now coming to Boston. The site aims to unify women and men who have experienced street harassment (you know, whistling and the like). Hollaback! Boston officially launches December 7, so be sure to follow on facebook and twitter to join the dialogue.
