I surf craigslist in ny, for free wood, or discounted wood all the time.
This organization seems to get job leftovers, over stock, donations, whatever, things that end up in a dump somewhere.
They claim to offer it at less than half regular price.
For someone like me, this could be a good source of lumber, cheap pt or pine, maybe some oak. Dont know, Im going to take a ride this week I think.
