The commercial corridor running south from Saratoga Springs toward Malta and Ballston Spa wakes up before it is light, and in winter that means the lots have to be open before the first shift arrives. Yard Work N More Property Services Inc plows and salts those entrances, aisles and walkways in the dark hours, then comes back to the same properties in summer to mow the lawn panels, trim the islands and edge along the curb lines. Cleanups in spring and fall clear the sand, the leaves and everything the year piles up along a fence. It is steady grounds keeping — the sort of work people only notice when it stops. Around Saratoga Springs it does not stop.
