Two children are being treated for injuries at an Atlanta hospital following an accident on Lake Lanier between a personal watercraft and an inner tube pulled by a boat. A boy, age 11, was unconscious after the accident in the Van Pugh Park area and was airlifted in critical condition to Children’s Healthcare of Atlanta at Egleston. A 15-year-old girl was treated on the scene, said David Kimbrell, Hall County Fire Services chief and Emergency Management director.
