Inmates exercise in the main general population yard at the Pelican Bay State Prison near Crescent City, Calif., Wednesday, Aug. 17, 2011. State prison officials allowed the media to tour Pelican' Bay and its secure housing unit, known as the SHU, where inmates are isolated for 22 1/2 hours a day in windowless, soundproofed cells to counter allegations of mistreatment made during an inmate hunger strike last month. Inmates in the general population yard are allowed more access to exercise than those in the SHU. (AP Photo/Rich Pedroncelli) less
