The platform at North Wilmington starts filling a little before the train does, coats buttoned, breath showing, everyone counting on the road behind them having been open. L&M Landscape works the hours that make that possible — plowing driveways, shoveling walks and steps, spreading salt and sand where the tread goes slick at the bottom of an incline. When the snow finally quits for the year, the same properties get mowing, trimming, edging and the cleanups that carry them from mud to green. There is a plain pleasure in the handoff: the last plow route in March, the first cut in April, the same houses either way. Wilmington keeps its schedule, and this is part of how.
