Ok on the source for the big buck info, and thanks for the explanation. If the guy invites you, and says go for him, then git 'r done and be happy to have such a friend... As a landowner, I'd much prefer that my guest put a tag one of the big bucks hanging around, rather than never get to hear about it because some poacher did his dirty deed...
