Winter strips the timber south of Mount Vernon down to gray bones, and when the ice arrives every branch out toward Bonnie and Ina wears a glass sleeve. KV Trees, LLC spends those hard days on the ground — plowing drives, opening walks, cutting a path from the door to the car while sleet still ticks on the hood. A storm here can turn a driveway into a slick inside an hour, so treatment goes down and the low spots get watched. Late afternoon the sky turns the color of pewter and the world goes very still, and a cleared drive is the most welcome thing in it. That is the work: making a hard morning ordinary.
