On a July evening the Mystic Lakes hold the last of the light far longer than the streets do, and the hillside above them cools while the water is still bright. Suburban Yard Specialists keeps Winchester's yards in step with that long evening — mowing on a dependable rhythm, trimming and edging until the lines are unmistakable, mulching the beds, and clearing everything out in spring and again in the leaf season. When the lakes go stiff and gray, the same crews turn to plowing driveways, opening walkways and putting down salt and sand where the ice takes hold. There is a version of a property where nothing is out of place and nothing looks fussed at; that is the target, summer and winter alike. Getting there is a matter of showing up on the right day, again and again.
