On a June evening in Oradell you can hear the Pascack Valley train slow into the station and, underneath it, the last mower of the day winding down. Joe Amaral & Sons Landscaping Inc. keeps to the borough's short blocks off Kinderkamack Road, where front lawns are small and every uneven strip along the sidewalk shows. Mowing, edging, trimming and cleanups run from the first push of April growth to the last oak leaf in November. Then the season turns and the same trucks come back with plows, opening driveways and walks and putting salt down before the morning rush finds the hills slick. Bergen County weather rarely gives much notice; the answer is to be out in it early and to leave a street looking looked-after.
