I was eyeing a downed hickory tree but the owner said she was going to keep it. This was going to round out my wood being split and seasoned for next year. I know of a tall cherry tree I am sure I can get but wondering if cherry is a wood for filling a firebox or just to add a piece here and there? It's a big tree (for a cherry) so will be a large portion of next year's wood. Should I put the time into the cherry or go find something better? Sycamore - I don't see sycamore listed on the "btu" list recently posted. I split up a dozen or so logs and wondering how good a wood it is, comparatively speaking? It is unseasoned right now but seems like it might end up being a fairly light wood.
