Imagine spending 23 hours each day alone in a 6x9 ft space. Crowd into it a toilet/sink combo, rusty iron set of bunk beds, and overhead lockers... layers of peeling paint in multiple colors, showing the years of neglect, black mould, roaches, rats, along with spiders and bugs I can't even identify – then you'll have some idea of what home looks like to many people here in Texas' Eastham Unit.
