Start with the ground itself. Commerce City sits on tight Adams County clay, a mile up in air so dry it pulls the water back out of everything by afternoon — grass that stays green here is grass somebody paid attention to. Mount Sinai Landscaping & Concrete LLC keeps yards going on that ground with mowing, trimming, edging and the seasonal cleanups that stop a lawn from getting away from you in the long heat of August. Around Derby's old grid the lots are small and the sidewalks run close, which makes the edge the whole story: one straight, deliberate line where turf meets concrete, crisp enough to read from across the street. It's plain work and it shows immediately, which is most of the pleasure of it.
