There's an hour in late June when the light comes level down Market Street and every strip of grass in Marcus Hook turns the color of a struck match. Baldwin's Lawn Care works that hour and the ones before it — mowing, trimming along the sidewalk seams, edging the front walk until the line is sharp enough to sight down. In a borough this tightly built a lawn is measured in a few good steps, which is exactly why the details show. Clippings get cleared off the concrete, and the strip by the curb gets the same care as the square out front. Summer runs long down here by the river, and the mowing follows it through Marcus Hook, Trainer, Linwood and the blocks nearby.
