I once made the mistake of shooting a VERY large groundhog with a field point. I was only about 12 or 13. To make a long story short, tyhe field point didn't kill the groundhog quickly. As I was holding the ggroundhog down with my bow to get another arrow, he grabbed my bowstring and steel cables (Jennings Forked Lightning) and chewed them clean through in a few seconds. As he ran off to lick his wounds, I heard him muttering obscenities about stupid kids, and he vowed rvevenge. I don't mess with groundhogs any more for that reason. TRUE STORY!!!!!!
