A Cliffside Park back yard is measured in feet rather than acres, and the whole shape of it is set by where one property ends and the next begins. WK Fence & Lawn LLC works those tight lots in midsummer with the small machines, mowing right up to the line and trimming the corners out by hand so no ragged fringe is left behind. Done well, a yard this size looks bigger than it is — even green, crisp borders, nothing shaggy along the back. The crew keeps a route through the borough all season, then clears the beds and grass when autumn empties the trees. Lawn care in Cliffside Park and the towns just over its borders.
