Everything green in Limon grows behind something — a row of blue spruce, a line of elms, a shelterbelt set square against the west wind. Structures Unlimited, Inc. handles lawn care in that sheltered ground: mowing on a steady schedule, trimming close to posts and foundations, edging the walks, and clearing away what the wind drops. Out here turf is a choice, held onto season by season, and it shows plainly when somebody keeps at it. A cut lawn with clean borders reads like an argument won against a very large sky. Limon and nearby — Genoa, Arriba and Flagler.
