The Silver Comet begins in Smyrna — an old rail bed turned to pavement, running west past backyards and pine stands. Carter Landscape Services keeps many of those backyards, arriving on a schedule you could set a watch by: mow, edge, trim the fence line, blow the walks, gone. Summer here is humid and fast-growing, and a skipped week shows on the lawn; the answer is showing up again with sharp blades. Autumn turns the job to leaves, raked and hauled until the turf shows green underneath. Riders on the trail pass a stretch of town that looks looked-after, and that is the whole idea.
