When I was a kid, my dad picked up 6 of these exact trees.
Within 10 years they were already at 70 foot. Straight up growers and not much in the way of "finely branched" like their other tall growing counterparts...
He then decided to have them removed. That was the first time that I watched someone climb a tree,, I was around 14.
But those trees were nowhere near big at the base at what yours were. And out of all the work involved in tree removal, getting the stump flushed with the ground is the part I hate the most.
Brother, when I saw the diameter of those trunks you had to remove, I really felt for you all...
