I'm not against it though, are there ok alternatives I could try. I currently have as much wood on my property as I'd ever need, including straight white pines that need thinning, and red oaks that are dying. Neither of those woods are super rot resistant, but might work if I were to dig them in and cover them with a plastic moisture barrier right?
