In the Clifton Knolls cul-de-sacs the yards run together with no fences, so one shaggy lawn is visible from four front windows. James' Lawn Services works with that neighborhood grain — weekly mowing, trimmed fence lines and foundations, sharp edges at the drive, mulch in spring, leaves out in the fall. When the weather turns, those same driveways get plowed and those same walks get shoveled and salted before anyone has to leave for work. Knowing a street in both seasons is its own kind of local knowledge. Clifton Park, Elnora, Jonesville, Halfmoon and Round Lake.
