At three in the morning the causeway over Muskegon Lake is a string of orange lights laid across black water, and the wind is already carrying more snow into town. KL Excavating LLC is out under that sky, plowing drives and lots so the first shift of the day finds bare pavement instead of a problem. Snow off the big lake rarely falls straight down here; it comes in sideways, and it will refill a cleared approach by breakfast if nobody is watching. Salt goes where the wind polishes a surface to glass — the turn at the top of a drive, the shaded corner of a lot. The whole reward is a clean rectangle at dawn and a customer who never had to think about it.
