Look up Dave Canterbury. He posts through YouTube. From what I gather he is is either a former ranger or SF. His vids are very good and he deserves a shot at this thing. He goes by the screen name Wildernessoutfitters. Look him up you won't be disappointed.
History is a freak show and a dark comedy. Mankind is a spectacle all to itself. Play your role, let the jesters play theirs. In the end...who has the last laugh?
