I talked to my wood guy the other day to see if he had some oak in. He called me back today and said he had some red oak (my favorite) and to come over and pick some up. While I was there he through in some cherry, mulberry and some white ash. I haven't used ash yet so I'm interested to see how well it burns and what flavor it will embark on the product. Not a bad haul for $25. It filled my S10 pretty good.
