Legendary prison located on an island in the San Francisco Bay. Also known as "The Rock." Its about 1.5 miles away from the city. The prison had to be closed down because too many inmates were successfully busting out of the complex. The designers of the prison were stupid because they decided it was cheaper to use recycled salt water in the surrounding bay, instead of fresh water to flush the toilets. Thirty years of salt water saturation lead to erosion in the buildings, which meant that inmate Frank Morris and his buddies were able to dig holes in their cell walls with spoons, escape from the vents into the utility corridor, climb onto the roof, and bust out. The defunct prison is now a tourist attraction in San Francisco.
