September, and the days start giving back four minutes at a time. Down along the Edison Sault canal the water runs at the speed it always has while the lawns above it slow right down. Glaciers lawn care keeps to the rotation anyway — mowing while there is growth left in it, trimming around fences and foundations, then the long cleanups when the leaves come down all at once. Grass in Sault Ste. Marie gets a narrow window and uses every day of it, so the work follows the light: earlier starts in August, later finishes in June. Even, tidy, and holding its shape the whole way through.
