Two seasons ago on the largest buck I have ever seen in the wild.....I am about 15 ft up in a tree on top of a very steep, high bank overlooking a small stream. Deer came to other side of the creek at a very steep downward angle putting him about 30 yds away from me (on the slant) but only about 10 yards out fromthe vertical plane of the tree. Trying to remember all the geometry involved in shooting at such an angle I shaved a double handfull of hair from his left side/chest when I held way too low on him. I am 58 yrs old and that is the first time I ever actually cried over missing a shot!
