Maybe I can catch that show later on I hope. I need to get out some of my old hunting magazines. I suspect there are different views on core areas and the average size of a core area. For example perhaps the largest and maturest buck I tried to hunt for 3 seasons seemed to change his core area each year. The last season I saw him he had moved close to 3 miles away and happened to be in a smaller area I could hunt. Never did get a shot at him.......what a buck.
