That guy cutting the top out of the tree looked like me several many years ago. We had a white pine that had the top broken out during an ice storm (many years prior to us deciding that the tree needed to go), anyway, a large branch grew out at an odd angle and was really tall compared to the rest of the tree. I climbed the perverbial ladder(the limbs grew out of the tree like rungs on a ladder) and made it to the top, pulled my chainsaw up to me with a rope and proceeded to cut that tall off shoot out of the top of the tree. I underestimated how much that thing weighed and when it left the tree it flung me around in the top of that tree and I was clinging for dear life. How it didn't shake me out, I don't know. I learned a very valuable lesson that day.
