Ken Kesey said when you take something out of the forest, the forest takes something out of you. Beware.

I'd fell it directly toward where your picture was taken yesterday. I wouldn't climb anything. I'd soak the ground and then dig out the root stem until you can see major roots running away from the street. Chainsaw those, keeping the saw blade out of the dirt.

This will lever the root up out of the ground and you can cut the rest and backfill. Make a smokeless fire pit and make activated charcoal.

And for pity's sake, put a composting outhouse in the back yard.
