One Man's Trash is Another Man's Treasure.

Score!  In the vain of trying to make this Tree house practical, and therefore affordable, I have been trolling Craigslist and found the motherload of used treated lumber from a guy in Warrenville that is selling the remnants of a play yard that he deconstrusted.  The lumber is only 6 months old, so this is a good buy.

Oh, and I only paid $50.  Check out everything that I got. 

I am so excited!  I will still have to buy additional (new) lumber for stuff I don't have yet, but this sure helps the budget to get things used.
