Sunset over the Route 59 corridor in December lands at half past four, and the lots empty into a blue dark that usually means weather is already moving in from the west. Sunset Services US is a snow removal outfit, so the shift begins where everyone else's ends: plowing lots and drives, clearing walks, spreading salt ahead of the freeze. Storms here tend to arrive overnight and quit near breakfast, which makes the whole thing a matter of timing — go out early, come back once more when it lets up. Morning is the proof, pavement showing black where six inches used to be. Aurora and the towns beside it, straight through the cold months.
