The Hutchinson River Parkway carries its stone-arched bridges through Harrison like something built by people who expected to be looked at. Navarra Landscaping holds to that same idea on the properties around them — mowing, trimming, edging and cleanups through the green months, plowing, shoveling and salting once the parkway turns white. Spring arrives here in a rush: forsythia one week, an inch of new growth the next, everything asking for attention at once. Winter has the opposite temperament, all patience and pre-dawn starts. Both ends of the year come down to the same thing — leaving a place looking looked-after before anyone is awake to notice.
