February on this part of the coastal plain likes to argue with itself: rain toward the shore, snow up the Turnpike, and East Windsor sitting right on the seam. Growing Concern Inc plans for the glaze as much as the drift, because a quarter inch of ice on a sloped driveway off Princeton-Hightstown Road can shut a house in as surely as a foot of powder. Plowing opens the ground; salting and ice control keep it open through the hard freeze that follows sundown. Steps and walkways get the same attention as the pavement, since that is where a person actually lands. The measure of a night's work is simple — the car backs out, and nobody slips getting to it.
