Tyler Hill sits high in Wayne County with the Upper Delaware cutting its valley a few miles east, and the air up here stays cool enough that grass keeps growing deep into September. Maciejewski Landscaping Inc. works that long green season — mowing, trimming, edging, mulching beds, and clearing leaves once the hardwoods finally turn the hillsides orange. Properties this far out are ringed by woods, so the line between kept and wild has to be redrawn by hand every single week. Holding that line neatly, with the ridges going blue in the distance, is most of the pleasure of the job.
