It's coming along! The entire house is framed, walled and wired with electricity. As with any of Weston's projects, it's all-consuming. If he has spare time - he works on the tree house and if he isn't working on it - he is thinking about it. I myself got a little caught up with looking at tree houses online trying to get ideas for the exterior. (Anyone interested in painting a mural of cottonwood trees? Anything to provide some camoflauge!)
Anyway - at least he is making progress!
