By two o'clock on a July afternoon in Walters the shade under the courthouse square trees is the only cool in town, and every sprinkler on the block is running. Stan's Pools mows through the hot half of the year — cutting the grass, edging along walks and drives, running the trimmer around posts and beds, and clearing the clippings before they scatter. Southwest Oklahoma turf takes the sun better when the mower is not scalping it, so the deck stays set high through the worst weeks. Evenings cool off quickly out here, and a yard cut that morning still looks fresh at sundown. Even lines, clean borders, nothing left on the concrete.
