Mist sits low over the coves of Lake Ouachita most summer mornings, and it burns off about the time the first engine starts. Dusty D Services LLC mows, trims and edges yards around Montgomery, on the ridge roads and the lanes that drop toward the water. The ground here is red and full of stone, so a lawn that comes in thick and even is something earned rather than given. The reward is the walk back to the truck at the end: clippings blown off the concrete, a straight line where grass meets gravel, the yard sitting quiet in the heat. Work like that asks for patient hands and a good ear for when the grass is ready.
