The blocks around Gumbert Park run flat and square, front yard after front yard, and on a weekday morning you can hear where the mowers are working from two streets over. C&B Lawncare LLC keeps that rhythm going through the Westfield growing season — cutting, edging along the walks and the curb line, trimming the corners a mower rounds off, carrying away the clippings and, later, the leaves. When the season flips, the same route gets driven in the dark with a plow on the front: driveways opened, walks cleared, salt spread where ice sets up overnight. Two seasons, one list of houses. It is satisfying work to look back at.
