Thornton grew on a plain grid off Washington Street — square blocks, real alleys, a town laid straight onto flat ground with the mountains parked on the horizon for scale. A grid is honest to work: you take it one block at a time and nothing hides. GKC Landscaping Contractors runs both sides of that calendar, with mowing, trimming, edging and property cleanups when things are growing, and plowing, shoveling and ice treatment when they aren't. Alley approaches and back walks are where winter work gets forgotten, and they're exactly where a stuck car or a bad fall happens. Doing the whole property, front to alley, is the difference between a job and a finished job.
