Here is a quick rendition of the classic Hornberg fly. A Wisconsin conservation officer, Frank Hornberg, developed the fly prior to the Second World War. I'm not entirely sure of the actual history of the fly or the man but I got the impression that this man was not one to share his secrets. I also remember reading that he had a particular dislike for any 'worm dunker" that dared to fish his hole. If anybody has more info on the subject - please inform us in the comments..
