Guerrilla Masquerade Party was a group dedicated to turning unsuspecting bars and other locations into giant costume parties -- adding more fun and frivolity into Seattle's nightlife, and creating new and creative spaces from 2003 through 2008. This email group provided information on when Guerrilla Masquerade Parties occurred, and where. It remains as a way for people interested in similar events (Santarchy, etc) to communicate. Messages to the group require approval, and average only a few per month.
