Last year, 21,000 inmates were released in Huntsville, Texas — one of the largest prison towns in America. For most of them, their gateway to the free world is the Huntsville Greyhound station.
Monday through Friday, the glass doors swing open on the front of the Civil War-era, red-brick prison they call "The Walls." The inmates exit and shuffle along the sidewalk, some smiling, some pensive, shouldering potato sacks full of belongings. Most of them don't have loved ones waiting, so they continue walking the two blocks to the bus station — single file, out of habit.
