On a related note, we were clearing a 1/4 acre lot by taking down the one large, spreading beech tree on it. Halfway through, a surveyor showed up to mark the corners etc. I was none too happy about sharing the small worksite with anyone but it was what it was and he looked up fairly often to try to stay of the way. So Im up in the bucket, we're roping piece after piece, a lot of em had a big swing as they grew out over neighbor's property and had to land in the middle of our lot, near the chipper. Well you know, on each cut, sooner or later you have to put all your focus on the backcut, you can't be looking other places and also cutting. So I go to make a cut, the surveyor simultaneously starts heading right thru the drop zone, oblivious this time. A hundred pound piece swings down and literally misses his head by 6". Holy shit, I lost it.
Epic survival story.
