What is a black walnut worth...anyone know? I had a guy ask me earlier if I wanted a black walnut tree that blew over in his yard. He said it is about 60-80' tall and nice, wind blew it over, stump and all. I told him my buddy would cut it up for firewood and the guy gave me a funny look and said he hated to see it used for firewood, that it was a nice tree. Just got my curiosity up as to what a tree like that is worth. Is it worth the time to remove it? Thanks.
