the same exact thing happened to me last year, it was a young spike and had slobber running out of its mouth and didnt even care i was there, my buddy reached for his camera but when he took the pic it actually was about 10yds away already but at one point it was 1 foot and it didnt even care i was there it had its head to the ground and was tracking a doe. when we told our other hunting friends about it they said yea right, i really dont think they believed us but it was true and probably wont ever happen again....but it was really cool.
Im 42 and never had anything like that happen to me and probably never will.....

Hunting with a bow brings about a different challenge on every hunt!!!
