Ultimate Real Tree House / Tree Fort Build - Part 1 - Platform and Support Structure

I promised I would build my boys a treehouse this summer and I couldn't let them down.  Watch along as they help me step by step build a structure that is supported only by the trees in which it stands.  This video is Part 1 and covers the construction of the support system and the platform that the tree house will be constructed on.  Continue the series in parts 2, 3, and 4.
