Snow in Chicago announces itself hours ahead. The wind turns, the sky goes the color of a nickel, and the forecast starts naming inches instead of chances. RJS Snowplowing Services LLC spends that stretch ready — truck fueled, blade hung, coffee going — because a plow route is won in the waiting and lost in the scramble. Then comes the long night of driveways and walks, the same rhythm again and again: drop, push, back out, salt the step. Morning arrives, the city moves, and the trucks head home while everyone else heads to work.
