October along the Fondulac riverfront smells like cold water and dry leaves, and the geese make their noisy arrangements over the marina. Green Fox Lawn Care is out in it, taking the last cuts of the year down clean, trimming the tired edges back to a crisp line, clearing the clippings and leavings off the walks. A few weeks on and the same customers wake to plowed pavement and salted steps instead of a lawn. The turn from mower to plow happens fast in this valley, which is why it pays to have one outfit that already knows where your culvert and your soft spot are. Tidy in fall, passable in February, that is the promise.
