Presuming I’m still in the tree, First, call my wife and tell her where I am and that if I don’t call back in 5 minutes I’m in trouble. Then I will try to get stable. If I can, I would reach for one of my 2 lineman’s or a Cranford rope step. Cell phone and climb options should be where they can’t get away. Hard to imagine, but it can and will happen. I dread the day already.
