San Quentin, the historic prison on the edge of San Francisco Bay, confines about 3,800 inmates.
726 of those are men condemned to death row. There's also the correctional officers, medical staff, cooks, chaplains, counselors and a very unique group of people: volunteers. Each month, thousands of volunteers come inside the prison to help run more than 70 rehabilitative programs.
San Quentin Radio is a project in which KALW editors train inmates to report stories from inside prison, with cooperation from prison officials.
