Saturday morning in Mechanicsville, the mowers start up about the time the coffee does. Reno Brothers Lawn Care handles the lawn side of Thompson life: cutting, trimming, edging, and the spring and fall cleanups that reset a yard twice a year. Grass on the low ground near the water grows thick and fast, and the route keeps pace with it instead of chasing it. Leaves come in a rush in late October and the blowers stay out until the light quits. A neighborhood where every lawn gets its turn simply looks like a place people are glad to live in.
