Four in the morning at Pines Lake, and the snow has been falling since before midnight. Aqua Gardens Landscape is out in it, plow down, headlights full of flakes, moving driveway to driveway along roads that bend and climb above the water. Streets like these ask a driver to know where the pavement ends before the snow will tell him. Walks get shoveled to the door, salt goes where the shade lets ice set hardest, and the piles get pushed clear of the mailbox. By the time the neighborhood wakes and backs out, nobody has to think about it.
