Down at the Coxsackie riverfront the tide actually turns — the Hudson is still salt-tugged this far north — and on a July evening the whole village drifts toward the water. Shortcut Lawn Care spends those long days on the grass: mowing, trimming, edging, spring and fall cleanups, and the steady weekly rhythm that keeps a lawn from ever looking behind. A yard cut on time is barely noticed, and that is the compliment. Miss it two weeks running and the whole property sags; keep it and the place just looks like summer. Being the reason nobody has to think about their lawn at all is a fine way to spend a season.
