I am going to build a treehouse for my two kids in the backyard this summer. i have already checked out numerous websites (see links), bought a book (Black and Deckers', How to Build a Treehouse) and rented one form the library (Treehouses and Playhouses by David and Jeanie Stiles). The kids are excited as am I. My wife is a little concerned about time and money. I'm throwing up a blog to keep track of the process.
