Like my emphasis on Bowhutnign at my seminars, wheter bow or Dangerous Game and a Back Up Rifle:
SEC
1) Safety (for you and others)
2) Ethics for the Sacred game and you and
3) Common Sense ( It is the LAW)
to hunt Grizz with bow without a back up is....
Not Common Sense .... like snow boarding where Avalanches are prevalent and then expecting someone to rescue you.
NEVER,NEVER UNDERESTIMATE YOUR QUARRY OR OPPONET.
