I have cut one tree down for the value of the wood some years back.
It was a large black locust, totally covered in burls. Black locust is an introduced species here and not very common, the burly ones even less so.
It would have been a good deal, if the owners Porche hadn't been blocked up for storage under a tarp beneath the tree. Not the kind of car you want to drop a branch on, so the takedown took just about forever.
Still, I got some nice wood out of the deal, that in due time was coverted into bowls and sold.
