It was just after 1:40 a.m. The temperature had dropped below freezing, turning the asphalt silver beneath the moon. I had pulled into a nearly abandoned highway rest stop — one vending machine flickering weakly, one broken light buzzing overhead, and miles of open darkness stretching in every direction.
I shut off the engine and leaned back, planning to sleep a few hours before finishing my route to Denver.
That was when I heard it.
Scratch.
A slow dragging sound against metal.
I opened my eyes immediately.
Wind, I told myself.
