The train tracks were two buildings behind his in St. Paul, but Sam could feel how close they were by the tremor that made the bed frame vibrate. The cars of the train lumbered, and the more Sam squeezed the bedpost, as if to make the vibrations stop, the closer the train was and the harder it became to ignore the thought of his deceased father, which came now at an inopportune moment. Sam could feel the slow movement of the train, as if the tracks on which the train rode were the bones along his spine.
