By late June the evenings around Greencastle stretch out long and warm, fireflies rising off the back lots, and every yard in town is doing its level best. Turf Medic LLC works only that side of the year — mowing, trimming, edging, and the seasonal cleanups that keep a lawn from getting away from the people who own it. Turf here grows on good valley ground, and it answers well to a regular cut at the right height, week after week, without fuss. The satisfaction is small and repeatable: a straight edge along the drive, clippings swept off the walk, a yard that looks settled. Greencastle and the places just up the road get the same treatment.
