Fog lies low over Black Creek on a Byron morning until the sun comes up over the fields and lifts it off the grass. Bayron Landscaping LLC starts the day's mowing about then, working the yards between the hamlet crossroads and the roads out toward Bergen and Stafford. Each visit takes in the trimming a mower cannot reach and the edging that returns walk lines to a firm border. Seasonal cleanups carry the heavy work in spring and again when the leaves come down across the flats. A finished lawn in that broad Genesee County light — even, tidy, its lines running true — is worth the early start.
