Lake Champlain stays open long after the fields have gone white, and all winter the water keeps throwing weather at the west shore. Green Thumb Landscaping & Snow Inc takes the year in both directions: plowing driveways and lots, shoveling walks and entries, sanding and salting the packed ice — and then, once the frost lets go, mowing, trimming, edging, mulching beds and clearing out everything the cold broke loose. Farm fields and village lots ask for different things, a wide turnaround here and a narrow walk there, and both want to be done before the day gets moving. By March the sand gets swept off the walks it spent the winter protecting. That's the sign the other season is coming.
