I've spent a while inside exploring the Cityplace Complex in Tulsa. It's just as bad on the inside.
Here's Fort Worth's highrise jail.

I've also been inside here as part of a tour with my college. I actually was depressed for days afterwards, seeing how these people lived, worked, walked around with chains, knowing they had families, and that some of them had taken and ruined lives. Some of the prisoners were sticking their arms through the bars, begging for anything and declaring innocence. Incredibly dreary atmosphere.
