West of town the Flint River bends slow through Flushing, and September along it is the kind of working weather you would order if you could — cool mornings, dry afternoons, grass finally growing at a pace a person can match. R & R Lawn Maintenance does the mowing, trimming and edging through that stretch, then the fall cleanups, then the changeover to plowing and shoveling once the river fog starts coming up as frost instead. Two seasons, two sets of equipment, one set of driveways to learn by heart. Knowing where the culvert sits and how the wind loads a particular yard is worth more in February than any amount of horsepower.
