Rocking D Services works the streets of Arco under Number Hill, the bluff above town where every graduating class has painted its year onto the rock since long before anyone now living can remember, so the hillside itself keeps count of the winters that have passed through this basin. Main Street sits narrow and short between the highway and the river, and the crew clears it end to end before the gas station and the cafe start seeing their morning traffic. Wind off the Lost River Range funnels straight down through town some mornings, scouring bare pavement in one block and burying a driveway solid in the next, so the route changes by the day more than the calendar would suggest. The Rocking D crew plows the in-town lots and driveways at the base of that bluff, working the same tight grid the town has kept since it was laid out along the railroad, while the ranches out on the flat get their own separate pass. The numbers on the hill catch full sun again by midmorning, and the streets below them read so clear that nobody driving through would guess how hard the wind had worked the night before.
