That made me nervous watching him back cut that tree with no real undercut. I was just waiting for it to start ripping apart. And then it starts popping... I didn't like him standing under or on top of that trunk while he was bucking it either. I probably would have done the same thing, what else would there be to do, but watching someone else do it is hard. Anytime there is something dangerous or questionable to do I have a really hard time letting other people do it. I just want to yell "stop that's dangerous!" And then do it myself, lol.
