Everything in Avon passes through the circle where the highways meet, which means a January squall crossing the Genesee Valley becomes a public event by morning. Cook Enterprises plans for that night — plowing driveways and lots, clearing walks, pushing the banks back so the pavement stays wide as the winter piles on. Come April the same properties want mowing, trimming and edging, plus the cleanups at both ends of the green season. Two trades, one habit: show up before it is convenient and leave the place usable. There is nothing showy about a driveway opened at five in the morning, and nothing more useful either.
