Probably a bit of a stupid thing to do, but I did it anyway. Had a sweetgum at the far end of the back yard that had died last summer in our drought. My son and I started pulling some of the branches with a throw line and at one point hit a crotch that was perfect for pulling the whole tree. Move the fence and cut. As a last minute decision, I thought, better get helmet and glasses. Notch, backcut, perfect except for the 3" 6' long dead branch that broke apparently as the tree passed the tips of the neighboring black gum and launched it back at me. Kask did its job, branch glanced off and thumped my shoulder, so I guess I'll have a pretty good bruise there thanks to plavix, but the alternative was avoided. Moral: always, always ALWAYS wear your PPE.
