Tim, Gri22ly, Buckeye, and the Duke all bring up good points. There is no doubt in my mind that bucks in more opencountry have a much larger core and home range then say a hardwoods buck in MI. Put some pressure on a mature buck some where like Kansas and his new core area will be 2 miles away in the next little patch of woods or worse in the middle of a field out in no mans land, not to be seen again till next season.
