The Silver Comet runs straight through Yorkville on the bed of the old railroad, and the land on either side begins its slow climb toward the Paulding hills. Williams Services LLC keeps lawns along those ridges and hollows — mowing on slopes that don't forgive a careless line, trimming the banks and fence rows, edging drives back to something clean. Spring comes in green and fast here, and by June the grass will get away from a yard inside a week if nobody is watching. Blowers finish the job: walks bare, drives clear, clippings kept off the road. Between Dallas and Rockmart it is the same simple promise — show up, cut it right, leave the place better than the hour before.
