According to a Daily News article from 12/26/1979 entitled "Has Progress Stopped His Autumn Night Rides? The Galloping Ghost of Vermont”, phantom galloping used to be heard on Wadlow Gap Road in the fall in the Bloomingdale Community outside of Kingsport, Tennessee.
The article documents that the ghostly hoof beats belonged to a Confederate soldier who was sometimes seen on horseback galloping towards the now disappeared Vermont Pond, where he would simply vanish. Folklore maintained this was the spirit of a young Confederate soldier union guerrillas chased down and shot at the pond.
The article proposes an excellent excuse for why the phantom hoof beats have not been heard since the mid-1970s: “. . . it may be that time and tide, waiting for no man or ghost, has covered over his echoing [hoof beats] with industrial sounds and the roar of traffic . . .” (Daily News)
