I grew up about 15 miles from Cadiz Ky where Harold and David are from. They were definitely local legends back then when Harold won the world goose calling championship. About the only place you could find turkeys in western KY back then was Land Between the Lakes or Ft. Campbell.
I went to high school with David Hale. He was older than me, and I remember when Harold Knight was a barber in Cadiz.
