For a few weeks each summer the town swells with people coming for the music, and every lawn in Lenox is suddenly on display. Pristine Properties keeps them ready — grass cut short and even, borders trimmed, beds edged and mulched, cleanups spring and fall — then turns to plowing, shoveling and salt once the visitors have gone and the roads run quiet and white. Winter is Lenox's private season, and the properties still have to stay open and walkable through it. The satisfaction lies in a place that never looks like it was caught off guard. Either half of the year, the standard holds.
