Beau, I'm trying to find out if The Haunted Mesa was ever out in audio book form whether on CD or Cassette. I read it over 25 years ago and most of his books years before that but I'm a truck driver and have started going back and revisiting his books in audio form while driving. I really like The Haunted Mesa and have tried to find it from a couple of Book dealers but no luck and when I check the Official Website it is not in the list of books but Amazon has hardback as well as paperback.
It does not exist in audio and may not. It is my opinion that when it is read to you it is not nearly as good as it is when you read all the words yourself. Education of a Wanted Man is a similar situation. The experience of active reading of these books is vastly preferable.
Beau, I truly think both books deserve an audio release, especially for those of us whose vision make physical reading more and more difficult as time goes on.
