A wet December snow loads the pines along Peabody's southern edge until the whole treeline bends and the streets go quiet underneath it. C & J Tree Services is out in that hush with plow and shovel — driveways cleared, walks opened all the way to the door, salt down on the steps where a slip would actually happen. Heavy snow is the sort that has to be moved early, before it sets up like concrete. The payoff is a drive you can back out of without giving it a thought. The city keeps moving because somebody was up first.
