My house was built pre-blight. I have a lot of chestnut inside, and I have a bunch of rails from an old stacked split rail fence around one part of my property. There's not enough to re-build the fence, plus they look pretty beat. They are, however, still amazingly solid-not punky. Cut and burn? Would definitely be seasoned! It seems somehow sacriligious. I should try to rebuild a part of the fence, but it's such a low priority on my long list of things to do around the place.
