A plow route reads like a map of a neighborhood's mornings: this house leaves at five, that one at seven, the corner double needs its walk done first. Land & Snow Services LLC works Cheektowaga's flat, orderly streets by exactly that kind of list. Plowing driveways, clearing sidewalks and steps, laying salt on the slick spot that forms every winter in the same place — in order, then again when the next band pushes through. None of it is complicated; all of it depends on showing up at three in the morning. By breakfast the street is a row of open driveways and nobody has to give it a thought.
