Isn' t it great physics is in everything. Math too!! Mayber after a few more years and I become a full blown engineer i can figure out a less complicated way to kill a deer. one that we won' t have to argue over which way is better. oh yeah there is one. a GUN. But, thats why I love bowhunting, the challenge and preperation that go into it. I cant just go blast away at the deer and kill it.
