Had an accident on my Harley
A friend of my family was killed in that exact scenario by an impatient teenage punk.
He clipped Jim just as you described and somehow broke his neck, leaving Wife and three kids.
He was the best tree guy I have ever seen in action.
He could climb a 80' pine like a monkey with his harness, spiked boots, and chainsaw clipped to his belt cutting branches as he went up.
Then would whittle the trunk on his way down till nothing was left.
He did not play games with ropes and stuff, amazing to watch, real tough guy, never would have thought someone could take him out that easily.
I would love to ride a bike but too many azzules out there.
Lot of azzules on bikes too, specially the youngins.
