I am a volunteer at KALX 90.7 FM in Berkeley, it's the UC Berkeley College Radio Station. You must complete 12 hours of work a month, so I write Public Service Announcements for hours. What's better than a PSA for SF Zero?

Play the Game: San Francisco Zero

SF Zero is a Collaborative Production Game. Players build characters by completing tasks for their groups and increasing their Score. You can choose from groups dealing with nature, art, movement, technology, or humanitarianism. The goals of play include meeting new people, exploring the city, and participating in non-consumer leisure activities. This is a free experience, open to the public, no matter where you live.
