Stand in the right spot in Deerpark near evening and three states are in front of you at once, New York giving way to Pennsylvania and New Jersey across the water where the rivers meet. Mystic View Landscaping mows the yards that look out on all of that, working late enough in the day to see the ridges go blue behind the town. Beds get edged, fence lines get trimmed, and the mowing lines are laid out to follow the lay of the ground rather than fight it. Spring and fall bring the bigger sweeps — winter debris pulled out, leaves cleared, the lawn handed back to the homeowner in good order. A view like that deserves a foreground worth looking across.
