There was a plethora of so-called sighting during the fifties and sixties…usually Wilbur or Virgil from the mountains of Kentucky

You may be thinking about these cases:

The Flatwoods Monster (1952, West Virginia) – http://en.wikipedia.org/wiki/Flatwoods_monster

The Hopkinsville Incident (1955, Kentucky) – http://en.wikipedia.org/wiki/Hopkinsville_aliens

During the fifties and sixties there were plenty of other purported sightings of aliens around the world: the Australian Outback, a forest in California, a lake in the Canadian Northland, a New Guinea missionary station, and a lonely stretch of road in Tasmania. Although some were prominently featured in books at the time, all but Socorro, Flatwoods, and Hopkinsville have disappeared into obscurity.
