Late light in Boonton comes in sideways off the Tourne and turns a fresh-cut lawn the color of a green apple. Elvin Lawn Care works toward that hour. Mowing in even passes, edges run along walks and drives, beds cleared, clippings carried off rather than left to mat down. It is unhurried work with a visible ending: a yard that looks finished from the sidewalk and from the kitchen window both. Boonton lots are small and shaped by the hillside, which only makes the lines matter more.
