|Temple of the Blue Moon|
As wonderful as a treehouse would be, I still think I would prefer simply to build a replica of Thoreau's Walden Pond cabin. Although we do have big and old trees in our woods, the logistics of building and maintaining a safe treehouse would be tremendous. All things considered, I think I would prefer to stay on terra firma and think Henry's thoughts after him. Of course, I can't help but think of Thoreau's famous summary paragraph about putting foundations under our castles built in the air.
Nestled in the forest, Thoreau's cabin would still be a sanctuary in the trees. It would just be more, well, down-to-earth or grounded, if you will. The Walden house is basic and simple, which was Thoreau's whole point.
