Ardsley keeps a weekday rhythm — the fields at Anthony F. Veteran Park empty by mid-morning, the streets gone quiet, the village handed over to the sound of work. LT Landscaping fills that quiet: mowers on their circuit, trimmers along the curb lines, edgers cutting the drive back where the grass has crept over. Cleanups come in April and again in late fall, when the ground wants opening or putting to bed. There is a plain pleasure in returning to a street you cut last week and finding it still holding its shape. Around Greenburgh, that is exactly what a schedule buys you.
