The highway is dark. There are no overhead lights and there are no other cars on this stretch. Something made of highly reflective material catches my headlights. It looks like a loop, but I can't tell what it is.
Suddenly it rises, moves forward and comes down.
As I get closer I realize it is a person cloaked in darkness. It looks like a shadow moving in the night. With reflective cuffs on his pants. I never would have picked him out of the darkness if I hadn't seen those reflective steps.
