Some outfits pick a season. TrashGrassSnow.com LLC works the whole loop of the year in Ogdensburg — mowing, trimming and yard cleanups while the ground is green, plowing and driveway clearing once the St. Lawrence starts running ice. November is the hinge, the week the mower goes away and the blade goes on, and the whole town crosses that line together. Knowing a property in July makes the same property easier to plow in January: you know where the culvert sits, where the pavement stops, which corner always drifts. City properties and the roads out toward Heuvelton, Lisbon and Waddington are all served.
