The finest hour of a Mendham winter is the one after the storm: hard blue sky, sun climbing over the old Pitney Farm fields, every pasture fence line drawn in white. Sun Country Landscaping Inc. has been out long before that, plowing driveways and clearing lots while the sky is still the color of a nickel, then circling back to widen, square up and treat. Entryways and walks are shoveled so ice can't set on the north side where the shade lingers all day. By full daylight the pavement is dark and dry and the shovel can stay on its hook. That glare coming off a clean drive is the point of the entire night.
