A new coworker found out I enjoy this hobby, and has offered me the wood from a couple of small hickory trees if I'll cut them down. Sounded like a fairly good deal until he mentioned that the trees have been dead for a couple of years... So--is this still a good deal? Is wood from a dead tree any good for smoking? Is it already dried and ready to go, or is it something to stay away from? He has no knowledge of why the trees died.
