East of town the long ridge of Schunnemunk holds the first light, and by the time it slides down into the yards below, Armando Landscaping Corp is already unloading. Mowing here means reading a lot of small, sloped lots — grass that comes on fast in the Orange County damp and wants a steady hand at the borders. Trimming along fences and foundations, cutting a clean line where lawn meets walk, blowing the clippings off so nothing is left behind but the stripe. Cleanups bookend the year, spring and fall, when the maples let go all at once. From Palm Tree over to Monroe, Woodbury and Harriman, the aim is a yard that looks tended on a Tuesday, not only on the day the crew comes.
