A tree guy I know just dumped me off a cord or so of green wood, for free and freshly cut from one of his jobs. Some logs large enough for splitting, but much of easily-burnable size.
People who are not fireplace experts think you need kiln-dried split wood for heat or for fireplaces. You do not.
As readers know, I keep the fire going in the MF HQ from October to May. I keep a supply of split and outdoor-dried wood, but once a fire is happy with coals I like to burn either green or wet logs. More heat, less flame, slower burn. Green wood burns fine once you have some coals. Sometimes, I throw a couple of hunks of charcoal in there to keep it hot and happy.
