Two initials on a tailgate, and a stretch of Chatham County yards that know the sound of the truck. Summer evenings in Pooler come on slowly — cicadas winding up in the pines, the heat easing a half degree at a time — and there is usually one more lawn to finish before the light goes. D&B Lawn care and Landscaping LLC mows, edges and trims through that long green season, then blows the drive clean and moves along. The grass will be back in five days; that is the arrangement here, and it is exactly why the route matters. Pooler and the towns beside it keep the week full.
