In Lincoln the ground remembers stone — glacial boulders strewn through Lincoln Woods, old lime ledges under the hills, the long grey walls running beside Great Road down toward the Blackstone. Chad's Landscaping Inc. works in that same grammar: hardscape set so it looks like it grew where it sits, landscape design drawn to a yard's own slope and light, and upkeep that keeps a property looking the way it was drawn from the start. Summer is mowing and the clean green geometry of a lawn kept honest through July; winter is plowing, a driveway opened dark and early while the mill villages are still asleep. The pleasure of it is physical and plain — a bed edged crisp, a walk that holds its line, a yard that carries its season all the way through.
