Fowler Services tends grass in Castleton, Vermont — slate country, laid out between the wide blue of Lake Bomoseen and the low green shoulders of the Taconics. The work is lawn care and mowing: long passes across dooryards that tilt down toward the water, trim lines drawn close to old slate walks and stone steps, grass brought back into order week after week while the valley light moves across it. There is a plain satisfaction in what's left behind — the striped sweep of a finished lawn, edges cut sharp, clippings swept off the walk, a yard that reads as cared for from the road. From Castleton village out through Hydeville and Bomoseen toward Fair Haven and Poultney, that same tidy line follows them home.
