J. Jackson, known to his colleagues at the Walker County Sheriff’s Department simply as Jayjay, stuck another matchstick between his front teeth and began chewing on it. He unzippered his fly and issued a yellow stream into the dry bed of Bedias Creek. Steam rose from it in the cool morning air, and he made a bold effort to make sure that most of it crossed the county line into Madison. Somewhere to the north, beyond the trees that broke the monotony of the flat Texan landscape, prisoners were being called out of their cells at the Ferguson Unit to face another day of incarceration. And he was free to piss in the breeze, clocking off in just over half an hour, to bring to an end the long red-eye shift, and with it the prospect of an empty bed. He spat out the matchstick and regretted that he had ever given up smoking. He was sure to die of wood poisoning.The Dixie Chicks played from the open door of his black and white. Strictly nonregulation, but hell, you had to have something to keep you awake.
