The edge is where a lawn tells the truth. Late in the day, when the sun drops low over the Littleton rooftops and rakes across the grass sideways, you can see every line — the mow stripes, the clean break at the driveway, the trim held tight around the mailbox post. Grassthetics builds its whole week around that, cutting, trimming and edging yards until the boundary between green and concrete is a drawn line rather than a rumor. Colorado sun is unforgiving on turf and just as unforgiving on sloppy work, so the standard shows up in the light. Walk past at six in the evening and the yard practically has a frame around it.
