By the last week of November the oaks over Westfield have finally let go, and the curb lines fill with drifts of leaves deeper than the snow that follows them. Tree Services Westfield works that season on the ground — pulling the leaf blanket off the turf before it mats and smothers the grass beneath, running the final cuts of the year, edging the walks one more time, tidying the beds for the cold. Under a canopy like this one a lawn only holds if somebody keeps taking the fall off it. Then the yard goes quiet and the shape of the branches becomes the view. It is a good way to close out a year.
