Late summer evenings on the river go still and heavy, thunder muttering somewhere off toward the coast, the boat landings quiet until dawn. Grass grows hardest in exactly that weather, and a skipped week shows on the front of a house. Swamp Dawgs Lawn Care & Landscaping keeps a tight rotation through the humid months — mowing, trimming into the corners and down to the water's edge of a lot, every walk and drive cleared before the light goes. The truck pulls out and the place reads orderly from the road, right down to the last border. The Altamaha corridor and the towns near it are covered each week.
