Guy in the bucket was new to a 70', using a rope that was at least 20' short for the application, mind you there was a fresh 150' rope in his truck. He cuts a chunk of oak at least 2x the weight of the groundie, rope ran out on the guy, didn't have any wraps anywhere because the rope was already too short. Long story short he didn't let go, got lifted 10 feet, piece swung into him and knocked him unconscious, he dropped straight down and the piece landed on him. I heard today would have been his first Father's Day. Kiss the ones you love, and always break out the longer rope. You can argue about who's going to roll it up after the job gets done...
