Many area fire departments closed out their weekend—we hope—by responding to the 28th county grassfire in seven days which required a fire department response Sunday at 999 McGregor drive west of Knoxville.  Knoxville Township, Knoxville, Pleasantville and Columbia Fire Departments, Marion County Sheriff’s Deputies and Emergency Management Coordinator Jeff Anderson responded to the scene, which consumed approximately 20 acres of private property before spreading to federal property.  Crews had the blaze under control within an hour of arriving on scene.
