Anyone who has merged onto US-23 on a February morning knows what a Fenton winter can ask of a person. Dynamic Outdoor Services works the hours before that — plowing drives and lots, cutting a path from the door to the car, salting the shaded strip where meltwater refreezes by five o'clock.

The rhythm changes; the aim does not, which is to leave a place so the people living there never have to make an adjustment. Michigan weather is not subtle, and neither is the difference an open driveway makes at six a.m.
