Out where the Great Egg Harbor River slides past the old furnace ruins, the water runs tea-dark and the woods lean in on every clearing. Weymouth Township is mostly pine and river, so the lawns here are hard-won openings, and Guardian Landscaping, LLC keeps them that way — mowing, trimming, edging back the green that would otherwise take the yard. High summer in the barrens is loud with insects and slow with heat, so the cutting gets done early while the ground still holds the night's cool. A sharp line between a lawn and the woods behind it is a genuinely good thing to stand back and look at. Along Route 50 and the sand roads off it, that line gets drawn again every week.
