BostonSOS is a volunteer-run, free-to-join, social arts & event group.

How it works:

1. Join the site. It's free!

2. Come to a free event. How much do free events cost you? Nothing! #winning

3. Meet people with a sense of humor. Misbehave in public.

NYC-based guerrilla-performance group, Improv Everywhere was our initial inspiration when we started the group in January 2008. As we've grown we've taken in the philosophies from a number of other underground urban movements that share three common goals:

• Meet new people
• Have fun purely for the sake of having fun
• Make the community a more interesting place to be
