SJHUNTER, Here is a place that I see advertised in the classified ads of Bowhunter quite often. The website is www.oavideo.com . Here is the other info:
Outdoor Adventure Videos
10950 Deer Run.
College Station, TX
77845
Toll free phone is : 888-584-3363
The ad says that they have over 1,000 top name titles and they will send a free brochure. Maybe they will have what you are looking for.
My buddy and I have bought videos off of e-bay. Him especially. I know for a fact that he has bought videos by both Bob Kirschner ( matter of fact he got one about a month ago) and Alan Altizer. You might want to check there. He finds them in the hunting section. Does a search of VHS video tapes. Hope you find what you are looking for.
