U.S. Army Corps of Engineers Nashville District Park Ranger Brent Sewell rescued a drowning teenager from Martins Fork Lake, Smith, Ky., over the Labor Day weekend. Aaron Ledford, 18, a non-swimmer from Louisville, Ky., attended a family reunion Sept. 1 and entered the water to recover a beach ball. He got into trouble when he released the swimming area’s boundary line as he pulled himself out hand-over-hand.
