Son (with Littlest Kidlet as spotter and assistant and all of us on straps to guide each branch as it came down) has been working away at it because it is unattractive, full of galls (which I'm keeping for dyeing) full of spiders in the fall, and trying to grow an oak forest in our lawn. Any two or so of those would be grounds for termination in my universe (besides, we need the room for fruit trees) so it is going away.
Once the branches are cut we drag them to the back yard
Where it is (mostly) my job to cut them up as much as I can without sawing so that the bits can go in the chiminea. I'm considering renting a wood chipper so that we can mulch up at least some of it and speed up the process at the same time.
My intention was to replace this tree with a 'Dolgo' crabapple which has large, useful fruit but I'll need Eldest Kidlet to get pictures to show why the plan was changed.
