I can get some hackberry, soft maple, and elm firewood for free. I was wondering if I should even bother with the elm. I heard it doesn't burn very good at all. I've never burned it before, so is it worthwhile to cut, split, and haul it home? Or should I just grab the soft maple and hackberry? There's plenty for me to get. There's enough to last us almost 3 winters I'd say, so I can be picky.
