This will be the year of the treehouse for us. We really need to get one in out there. We have such a perfect yard for it-- half lawn, half wooded-- and I think it is a rite of childhood to build a boss-awesome fort / playhouse / treehouse. As a family we decided to go the treehouse route. So there it is.
We will keep a journal of it. This is definitely going to be a great engineering / naturalist / artistic homeschool project. Right now it's still in the decision making phase. We have very little sourced material so far, but I am going to see how free we can make it. This should be fun!
