So your furnace also heats your water, that is so cool. I hope you will not run out of wood.
I saw an old building that you are stacking wood under, is this an old place where people lived many years ago? If you can find where they buried their trash you might find all kinds of old treasures like old bottles, I have been seeing where people are digging up old outhouses and bringing out old bottles. I do not think I would go that far but an old trash pile is different to dig in. That is, when you find yourself with nothing else to do, (insert sarcasm).
When you have a farm, there is always work to be done.
