Abington sits a few miles back from the South Shore's salt air, on flat glacial ground where oak and white pine crowd against old shoe-shop streets and the water at Island Grove lies still enough to hold the whole sky. Cullivan Landscape Construction Inc. works the yards along those roads — mowing that leaves a clean line at the fence, seasonal cleanups that carry off a winter's load of oak leaf and pine litter and hand a lawn back its color. When the first hard storm blows in off the bay, the same trucks turn to plowing, opening driveways and walks before the streetlights blink off and the commute out to Route 18 begins. It is plain, physical work, and the proof of it shows from the road: an edge that stays crisp, a lawn that holds its green well into the heat, a driveway cleared down to bare pavement.
