I've got a pretty much unlimited supply of old Oak fence boards. This pile was getting ready to get the match. I usually plane them down and make display boards for trains. I was thinking about planing these down to use as flooring in my cabin. Cabin is not built yet. They are all 30 to 50 years old. Once I plane them I was just going to stack them tight in my shed, maybe ratchet strap them. I don't think mold will be a problem. What do you think, Joe.
