A few miles east of Mount Clemens the land simply runs out into Lake St. Clair, and the wind that comes back off that open water in January has nothing to slow it down in between. Greater Lakes Managment Services builds its winter around that fact: drifts that rebuild on the same side of a lot every storm, wet heavy snow one week and fine dry powder the next. The answer is plowing on a schedule the sky sets, walks and doorways cleared by hand, salt worked into the places where meltwater keeps returning. Nothing about a well-run lot announces itself — you notice only that the lines are visible and the entrance is dry. Mount Clemens, Harrison Township, Chesterfield and St. Clair Shores all sit inside that watch.
