Here is another interesting repair sample. I found this Pic on the net but I saw a very similar repair done in my neighborhood. A tornado had damaged a tree. Somebody (qualifications unknown) screwed the split together. In less than 5 years the tree had healed itself so that you could not see the screws. Tree bark grew over the hardware, leaving no evidence whatsoever of what had been done to the tree. It was amazing. However, I always wonder what would happen if the tree had to be cut for whatever reason. I have visions of an unsuspecting tree worker cutting into the hidden hardware and chainsaw flying all over the place. Quite dangerous.
