I don't know if you can find his tapes now, I went down and visited with him in the early 80's before he died, when he was living in Rawlins Wyoming. His son may have some of them around for sale, he was one of the first to teach others to howl and to have a set of howlers for sale, male, female and puppy. I went up and visited Crag and Dana O'Gorman, in Broadus Montana, as well in the early 80's he was a voice howler at that time as was Vern Dorn from Hanna Wyoming, Vern was one of the best at denning coyotes, Crag O'Gorman still is one of best coyote trappers, Bill Austin and Dan Thomson were some of the finest coyote callers you would ever meet. Bill Nelson, Gregerson, Patterson, James Lusero and others were some of the best trappers and snares men that the U.S. has ever seen. They lived with the coyotes and took great pride in doing their work to the best of their abilities, different times then we live in today.
