The Cocheco drops through the middle of Dover in a run of falls that once turned the mills, and in February the brick along the water throws the cold right back at you. Mourgenos Lawn Care is out in that cold with the plow, opening driveways and shoveling walks and steps before the workday can start. When the ice finally lets go of the river, the same properties need the other half of the year — cleanup, weekly mowing, trimming, and the leaf work that closes things out. Two trades on one calendar, both measured the same way: is the place usable, and does it look right? Cleared pavement in the dark and cut grass in the sun are more alike than they sound.
