I know a game warden who credits his kevlar vest with saving his life from a buck. The deer had been hit by a vehical and was injured badly on the side of the road. The warden came walking up and the deer half limped/drug itself down into the ditch near some woods. The warden went after the deer which caught him off guard with his back near a tree and basically pinned him to the tree. He is a rather big guy, and the points on the antlers did not make it through the vest, but he still broke a few ribs.

I met a guy in SC who had a buck in a high fence that he caught as a fawn. Deer was 4 years old when I saw him... and mean as a rattle snake. I turned my back near the fence and the deer charged the fence just like a damn bull... suprised me pretty good...glad they used good chain link fence. That was in mid September... so I guess his hormones were going already.
