My family had a sawmill in Idaho--until it burnt down and the family basically lost everything (many decades ago). We had a couple of those steam engines--one was donated to the county for hay rides during the county fair, the other was sold. We still have a couple of the old boilers. One ran the saw for the mill, the other was an engine that was driven into a footing for our ranch house, the wheels, etc, taken off, and then the house built around/on top of it. It heated the house through hot water radiators. We also have an old steam powered "truck" that my great grandpa built. It is pretty cool too.
