This reminds me of a story I heard from one of the hockey dads from my son's team (I won't use any names).
He works for (owns?) an excavation company. When he heard I was climbing trees, he told me he'd given it up 18 years earlier. Here's why:
He and another operator are working a job w/ a big excavator. The job is an old farm that's been sold off to a developer and I guess they're digging basements or something. Well, the farmhouse turns out to be of some kind of historical significance, so it can't be demo'd. Has to be moved.
Moving crew shows up unexpectedly and there's a big panic over who's going to remove this big tree that's in the way. His young partner takes off after the tree w/ the excavator and starts tearing branches out. But he can only reach up like 25'. So this hockey dad decides he'll ride in the excavator bucket w/ the chainsaw and cut the top out. First couple cuts went OK. What he didn't realize was that the big multi-pair telephone cable that the tree has grown into was putting a big side load on the tree. Care to guess what happens next?
Yup, his first cut BELOW the telephone cable releases that part of the tree, it shoots sideways, and it just cleans him right out of the bucket. Lands on his back where, fortunately, he'd removed a picket fence before going up. I guess we can give him credit for having at least a partial plan. Unfortunately, the 4x4" stub that remained fractured his arm.
But wait, there's more. Horrified by what just happened, the other operator jumps out of the excavator and comes running over to hockey dad (who's still laid out on the front yard). Remember the chainsaw? It's still running in the bucket. While the young guy is leaning over hockey dad, the vibrating saw falls out of the bucket and comes crashing down on his head, and then gives hockey dad a "duelling" scar right across his face. What a train wreck...
He can laugh about it now, but I'll bet there was minimal chuckling at the time. The two both survived (with minimal scaring from what I can see). Still digging holes, but subing out the treework.
