I was in a couple of heavy industrial parks in Pittsburgh this week and noticed several piles of wood from over seas shipping containers. Some of it looked like metric sized 4"x4"s , long lenth. I bet this wood would be given away to a person who just went and offered to clean the mess up. One pile looked like enough to frame up a small pole building. The stuff that was too small to use in construction could be used for firewood. I saw alot of rough cut oak in a broken up pallet pile, good hard wood for heating.
