Bears.  The true alpha.  Without our brain we are nothing compared to a grizzly bear.   You can’t really outrun them, they “kind of” can’t climb trees but I’m not willing to bet me life on it.  I just finished the Lewis & Clark journals and they didn’t know at first that black bears and grizzly bears were a different animal.  After they shot at a couple they soon learned to stay away from them, they weren’t black bears.  They were something different.  Here’s a horrible story out of Jackson Hole. – Forrest
