From the high ground on the west side of Putnam Valley the land drops away toward the Hudson Highlands, and on a hazy August afternoon the ridges stack up in paler and paler blues until the last one is barely there. New Views Home and Lawn Care keeps the lawns that own those outlooks — mowed clean to the drop-off, trimmed along the rail and the rock, edged where the beds meet the grass so nothing interrupts the view. Cleanups in spring and fall clear the hardwood litter that blows uphill and collects against the foundation. A lawn on a hilltop is seen from farther away than most, and it is worth cutting like someone is looking. Usually, somebody is.
