Six men. Six jobs that put a person alone in the dark. A solo elk hunter in the Weminuche Wilderness of Colorado who heard his dead brother's voice from twelve feet behind his treestand. A Utah Department of Transportation grader operator on US Route One Ninety One who saw his coworker standing in the headlights while talking to that same coworker on the radio. A nineteen year old kid alone in a lambing barn in Wyoming who answered the second time the voice in the dark pasture used his mother's name for him. A long haul trucker on the loneliest road in Nevada who refused a hitchhiker outside Austin and saw her again sixty miles up the road in the same windbreaker, holding the same bag. A relief lookout in a Forest Service fire tower in the Ruby Mountains who sat under the desk for hours while a thing wearing the regular lookout's voice walked the catwalk in a slow circuit. A ditch rider in the bosque south of Socorro who came around a bend at four in the morning and saw a man crouched at his head gate in his uniform, with his name stitched on the patch.These accounts come from people whose work put them alone in remote country with nothing but a radio for company and the next set of headlights hours away. The records they left behind are the kind that sit in the bottom drawer of a dispatcher's desk, in paper files in the basement of a substation, in internal memos that don't bother to give a reason because the people who needed the reason are gone. Six accounts that came in over the radio when the radio was the only thing left.If you work nights, if you drive long, if you have ever taken a shift somebody else didn't want to take, this compilation is for you. Settle in. Lock your door. Sleep with whatever light you need to sleep with.
