Ed, after studying the dead (white) tree from many angles, decided the only thing keeping it up was vines from the adjacent trees. We decided today was the day to free it! As Crystal and I whacked our way through the tangle of vines, we became cautiously optimistic that today would be the tree would be released from the evil grip of the vines.
Here is a video of the tree coming down. We were successful!
The back yard is a happier looking place now! It makes me want to go out there for a picnic!
