September is the town's best-kept secret — cool mornings, light turning honey-colored, and turf greener than it managed all August. Colorado's Greenest Thumb LLC works straight through that stretch and out the far side, mowing and edging and cleaning up around Terrain and the streets nearby until the mower gives way to the plow. Then it becomes drives cleared, walks scraped, ice knocked back before anyone steps out into the dark. A yard in Castle Rock asks for attention twelve months a year — just different attention each time. Keeping that thread unbroken is what the job is.
