Out by the Pottstown airfield the grass runs flat and open all the way to the fence line, and on a still morning you can hear a single small engine from a mile off. McWalters Landscaping favors that kind of quiet start. The days go into mowing, trimming and edging around town — yards, borders, the tight spots a mower will never reach — plus the cleanups that keep a season from piling up on itself. Wide open turf and a cramped side yard reward exactly the same thing: a straight line and a finished edge. By evening the cut smell is still on the air and the property looks like somebody meant it.
