A nor'easter reaches Somers around dark and settles in for the night. By two in the morning the hill on Route 202 is a white blank and the ballfields at Reis Park have disappeared entirely. Harter Landscaping of Somers is out in the middle of that, plowing driveways, opening the aprons the town plow packed shut, shoveling steps and walks and salting them down. The whole point is the moment at seven when someone opens the door, sees bare pavement, and doesn't have to give it another thought. Snow work for Somers and the surrounding towns, storm after storm.
