Main Street in Lawrenceville runs under sycamores old enough to shade both sidewalks at once, and the town keeps that unhurried, well-kept look in every direction off it. J&A Landscaping works those lawns, mowing, edging and trimming from the village blocks out to the newer streets across Lawrence Township. Mercer County sits on good piedmont ground, so the grass here genuinely wants to grow, and July can turn into a footrace with it. There is nothing complicated about the reward: a lawn cut at the right height, a hard edge along the walk, and clippings blown off the drive before the truck pulls away. Do that every week and a whole street begins to look like somebody means it.
