I used to do most of that, without the rope wrapped around the tree, the cage to get me into the tree, and the winch to pull me up the tree. That IS impressive work though, it takes being fearless but highly aware of your surroundings and a skilled ground crew to pull it off safely. There's NO room for error!
We used to drop the stalks like they did but often the way it was done back then, in closer quarters than that vid, the stalk would swing back and hit the tree below where the climber was tied in. Now that was scary, big time. Today the techniques are much improved and safer for the climber and ground crew, but still seriously dangerous work. When I see vids like this one, I can't really believe I survived the work over time. Every day could be your last. We basically worked with spikes, a climbing line and a lowering line, no helmets, no wrap the tree line, to keep from falling while climbing. One slip on the way up and down you came.:confused3: Phew, crazy times!
Glad to be alive. I always respect those who climb trees - nothing like it, exhilarating....
