Whitespider, I think I can comment on this thread on a couple of fronts.
I'm nearly 48 yrs old and have a 5 year old son. Not QUITE as ambitious as you, but nonetheless. :msp_tongue: My son wants to tag along with me EVERYWHERE. I'm sure yours is the same. Mom likes for him to tag along for obvious reasons, and I enjoy it MOST of the times. I have nearly 200 acres that is a giant playground for my family. When I jump on the quad (a 680 Rincon) to go out and buck or trailer rounds that I''ve already bucked, he drives the quad with me sitting behind him and at the ready. When bucking, I always make sure he is at a more than safe distance. BUT, when I know I'm going out and have to FELL trees, and many are dead standing Elm, he stays home. I have had life-altering wake-up calls on my own and want him to be no part of that experience. My "technique" has changed quite a bit after one particular harrowing experience. I ALWAYS back off, I ALWAYS have a clear route out, and my eyes are ALWAYS trained on that tree til it hits the ground and then some. Thinking back to my more invincible days, I can't believe I've done some of the things I've done.
A few years back, there was a retired PGH Steeler that lived near me. He died trying to save his Lab after it ran into "the zone" while he was felling a tree.
I'm not perfect fer sure. I have the scars to prove that I still suck at limbing downed trees. :msp_mellow: But please, have mom keep the boy, any other youngins, and even the dogs, attended to when you go out to fell a tree. It only takes a second fer sure. I'm sure that was a monster wake-up call for you. BE SAFE.
