By February the mouth of the Thunder Bay River has gone still and white, and the shanties out on the ice look like a small second town. That is the season Arctic Green Landscape & Design is built for — plowing through the dark hours, shoveling walks and steps down to bare concrete, spreading de-icer on the spots that glaze over every time the temperature swings. Wind off the bay can undo an hour's work in twenty minutes, so the trucks come back around, again and again, until the storm quits. What the neighbors see is only the result: a driveway that lets them leave on time. In a township this far up the shore, that counts for a great deal.
