A friend of the family is a taxidermist (she don't do fish), but is interested in 2 large White Oaks I have. If the cores are solid and you crosscut slab them to about 5-6" without wrecking the bark, the 4' tree could bring around 5K just for 6' of the trunk. She want's to know what the core is on a 6' White Oak I have. I had the tree doc out, and he believes the tree is rotting from the inside.
