OK I was doing a side job for a landscaper on a Saturday. Good friend not much of a tree guy. I was taking down a dbl lead read oak. I was working on getting the one side down. I had a peice of trunck a good 32" dia. by about 8 feet long tied on. The rope went up through a sturdy high crotch down through a limb about 15 feet out from the trunk. I cut the piece off and ground guy my buddy was just supposed to let it down into the drop zone of wood. Well the sun was in his eyes he says so he decided to hold it. I watched it coming back at me like a deer in the headlights hoping he was still gonna let it down. Well he never did. It was like getting hit by a car up against a tree. I was tears. I collected myself and got over the other side to finish taking down the remainder of the tree. It hurt for months, would put you in tears to press on it, I still feel it today when it cold out in morning.
I had no insurance at the time, going through a divorce paying way too much child support, already quit my job flying and couldn't afford to be hurt so I kept on working.
