Where the Poteau folds into the Arkansas at Belle Point, the river fog lifts around nine and leaves the west end of Fort Smith glittering. B & B Lawnscapes works that bottomland grass — the kind that puts on an inch overnight in June heat and is asking for the mower again by Friday. There is a real satisfaction in a stripe laid straight across a flat Fort Smith yard, and in the clean line where turf stops and driveway begins. When the sycamores let go in sheets each fall, the leaves get gathered and hauled before the first hard frost stiffens the ground. The whole job comes down to arriving while the dew is still on it and pulling away from a place that looks looked-after.
