I remember ol' Jim Conway and the huffing and puffing in the mic, must have had a cardiac condition! I also remember him calling to his son, "Stevo", all the time. That show jump started my fishin' career and I remember ads for the show in my early Northwest Fishing Guide books.
I know it was a KOMO TV 4 show like some other classics. Here is a link below to Captain Puget who also did Exploration Northwest if you remember that one. I know Don McCune's wife Linda is still active and writes a column (can't remember her e-mail address). She also has all the tapes of shows Don did. But I bet if you contacted KOMO TV and got connected with their archives or somehow contacted Linda you could get some answers how to get access to Outdoor Sportsman.
