We call that "built in kindling" around here.
Seriously, it's free. Split it, stack it, and let it season. Once it dries out, it'll all burn. Once it dries out, it will also slow the rotting.
If you were closer, I'd be happy to come take all that "rotten wood" off your hands.
LOL Wow...Rot doesnt burn I once tried it...you're talking about over seasoned which is fine but rot itself, nahhh, there's no heat or flames from rot, its pointless.
