I lost the biggest on the place a few years back from the straight line wind associated with a level 2 tornado .117 feet ,4 feet at stump level .Most of them in my little woods are right at 100 feet ,including the shag bark hickories .Some of the oaks ,red and white are 3-31/2 feet at stump . I think one big old burr oak is right at 4 feet .
I for one will not drop one just to prove I can do it .If it's not dead or a hazard it stays as it is .Those big oaks were 12 inches in diameter during the American revolution .I'd just as soon they stay after I'm gone .My great grand children might enjoy them .
