I had part of a tree taken down in my back yard last fall. The trunk is still there. If you want firewood, or you're into woodworking, it's yours for the taking. I live in Western Pennsylvania, so if you're in Australia you probably don't want it. But if you live nearby get in touch with me.

I'm afraid I don't know what kind of tree it is. But the trunk is about 7 ft long and about 6 inches around.
