I wish there were places like that near me!
Jim J. likes to taunt us with his local source, he even made a stand for the side of their dumpster to make his pillage even easier.

When I moved out of my former auto shop space many moons ago, I had a huge load of busted up OSB and other unworthy pine scrap. Nothing that could be used for anything but enough to house a Filipino village.

I leaned it all up against the outside wall in the evening when I was done clearing and was thinking about how many trips I'd need to take to haul it all off. 
Wasn't expecting anything, but put up a small sign with "Free wood".
The next morning when I came back it was all gone.
