From the WP:
The conditions inside the facility were reminiscent of a prison movie: stale air, dim hallways, only the bare necessities. The prisoners described getting about an hour and a half of physical recreation per day, but, depending on where you fell in the lineup for the yard, that could be cut to 45 minutes. Prisoners are allowed outside recreation only four months of the year: June through September. The rest of the year, they are told, is too cold to go outside. Because of lengthy construction projects, some inmates had not been outside for recreation time in more than a year.
On a day when outside temperatures reached 100 degrees, we quickly realized that cellblocks in most state correctional facilities are not air conditioned. It’s so hot that inmates sleep on the floor with their feet in toilet water. Rats infested the food and gnawed through walls.
