Oklahoma considers Eastern Redcedar an "invasive" species, and I was wondering if using it for cordwood building would be one way to turn that problem into a profit. A lot of my books are in storage right now, but as I recall, Redcedar was not on the list of Rob Roy's preferred woods. However, as you noted it is rot resistant, and, I'm wondering if it would be a suitable local resource in Oklahoma. Curious if anyone has used it. I'd "start small and chunk" and probably build a kids' playhouse or the face on a dugout root cellar first, but if folks have had success with it, I'd would consider it for a permanent dwelling also.
