I gotta boogie I gotta boogie I gotta boogie I gotta boogie on my finger and I can't shake it off.... Weird Al.
Reminds me of watching a documentary about volcanoes. A husband and wife team would walk among the lava flows to photograph lava, eruptions or whatever. I figured that is how they will die. this guy is taking a lot of risks that the rest of that tree has no flaws. What was gained at the end of it all? A worthless tree top was on the ground.
