The Rockaway River runs straight through the middle of Dover, and the low ground beside it holds the morning fog until the sun climbs over the ridge. AMP Landscaping Llc works both halves of the year here — mowing, edging, trimming and seasonal cleanups when the grass is growing fast in June, then plowing, shoveling and de-icing once the roads turn white. A lawn along the river flats greens up quickly, and there is pride in leaving stripes that run straight to the fence line. Come January the same trucks are out at odd hours making driveways passable for the first shift. Two seasons, one map, every street already known.
