Fog comes off the West Branch of the Susquehanna most summer mornings and lies in the low ground east of Lewisburg until the sun climbs the ridge. Scott's Lawn Care is out in it, mowing while the grass still holds the night's damp and the blades cut clean. Between the river and the farm lanes of East Buffalo Township this is country that rewards a straight line — long lawns, open sky, hedgerows to turn against. Trimming and edging finish what the mower starts, so a yard reads sharp all the way from the road. By the time the day warms over Buffalo Valley the work is done and the lines are still showing.
