The Normans Kill cuts a wooded ravine along the north edge of Slingerlands, and the properties that back up to it spend most of the summer in a green half-light. Conway Landscapes LLC keeps those yards — mowing, trimming and landscape work on ground that slopes and shades and grows in uneven bursts. In August the job is holding a clean line where lawn gives way to treeline; in February it is a plowed drive and a cleared walk before the school buses run. Yards with that much character reward somebody willing to learn their particular angles. Lawn care and snow removal in Slingerlands, Delmar and the Bethlehem side of Albany.
