I have about 20 8x8x14' long beams in my truck . They are 70 year old pine, I was going to give them to a guy to put up in his living room but he has no place to store them , So they are still in the truck . I was going to take them to the dump in the morning but i could cut them and burn them . The beams where stained but do not have a finish . I cant see them doing any harm if i burn them . If i had a old stove i would go for it. what do you guys think .
