Jackson's Clubhouse

The other day I came home from work and found a homemade ladder leaning against the front tree, some nails, hammer etc ditched up in the tree, and some old fence wood nicely laid out in the tree. Turns out it's the beginning of Jackson's clubhouse. He decided to do this after hearing about his cousin having a clubhouse. Wow! I was pretty impressed with his creativity, and will to get in there and just figure things out.
