On summer evenings at Beach Memorial Park the light comes in sideways, and every mowed lawn on the way home reads like a fresh page. Trumbull Expert Landscapers works those streets by day — mowing on a weekly turn, edging along walks and drives, trimming the fence lines, and clearing beds and leaves as the season shifts. There is a specific pleasure in the last pass of a cut, when the pattern closes and the yard is simply done. This town holds a lot of green, and green only stays that way if somebody keeps after it. That is the job, and it happens one yard at a time.
