According to Stephen Reid about his time in the US prison in Terre Haute, Indiana
I spent a record-hot summer locked down in what is known as I-Up, a long range of cells in a tin-roofed building well segregated from the mainline. I-Up houses all the bad actors and potential escape risks in transit from all over America. Three men to a cell, walking up and down in the yard every second day for 30 minutes in a dog run with a rusted corrugated cover. Indiana in the summertime, inside an airless concrete box. It didn’t surprise me that Terre Haute is where they eventually built a death house and sent Timothy McVeigh to his own hell.
