Old stone walls thread the woods around Postbrook, and by mid-October the oaks standing over them start letting go all at once. Vreeland Brothers Landscaping, Inc. works West Milford yards right through it — mowing while the grass still climbs, trimming and edging along wall and walk, then clearing leaves until the lawn shows again. Autumn in this township never falls in a single week; it comes in waves, and so does the work. There is something plainly good about the last pass of the year, when a yard goes from ankle-deep to bare, even green. In spring the same properties get opened up and started over.
