Congrats Novacule! It appears that you got the answer! Yes the nail is four feet in the tree! I see that you decoded my post message and saw the phrase "some things never change" and saw that the nail never changed places. Since that was a little fast, I decided that the person that explains why the nail is four feet, they share the title with Novacule for question number 2. And if Novacule also explains, he gets the title.
