After watching this video, http://www.youtube.com/watch?v=ehbSFnlDDfU&NR=1, and having done some similar drops yesterday on a smaller tree, it reminded me of my biggest fear in the tree, getting hit by a ricocheting spar. I've been hit before by smaller, 5' spars, one that smashed into my knee while freeclimbing, and find it to be the most dangerous part of being up in the tree. The heights don't bother me nor does the possiblity of falling. Getting crushed by something kicking back or swinging out of control does. Anyone else?
