I milled some cherry logs that had been sitting on the ground uncovered for four years. Blowdowns from a freak tornado that ran through Vermont about six years ago. I thought they were gonna be compost, mushrooms and mold on them, but the sapwood was shot and the heartwood was still really nice (and starting to spalt). I got a hundred BF or so out of four small logs, not bad for free. I know where I can get some more, too.
