Driving at dusk. Strong crosswind. Corner of eye sees whipping black canvas caught on wire fence. Thinks it’s a galloping horse, slams on brakes. Driving night highway. Construction zone. Dozens of plastic pylons throw swift shadows. Thinks it’s a hundred people running across the road. Slams on brakes. Enters unexpected tunnel. Slows down, 30 below the limit, to watch the pretty lights. Gets hit. Ruins two lives.
