Country mailboxes outside Harvard sit at the end of long lanes, and the strip of lawn between the gravel and the ditch still deserves a straight edge. Reliant Lawn Service runs its route by the week — mowing, trimming around posts and propane tanks, edging wherever there is a walk to edge. The mile grid makes a day simple: north a mile, west a mile, and every yard along the way looks better behind you than it did ahead. Spring and fall bring the cleanups, the season opened and then closed properly. Lawn care for Harvard and the farms and towns around it.
