The old stone walls of Winchester run straight through the woods below Platt Hill, marking out fields that went back to forest generations ago. The lawns that remain sit in the openings between them, and Beecher Construction Services keeps that grass cut, edged and trimmed clean around wall, post and ledge. Late May is the hard push, when everything grows at once and a week feels like three days. Beds get mulched, hedges shaped, clippings swept off the walk so nobody carries them inside. There is a plain satisfaction in a mown line that follows an old wall exactly.
