I am in the middle of joining 16,000 bd' of Northern Red Oak. I have enjoyed working with it greatly. It is quite heavy when "green" so material handling can be difficult to impossible without the proper equipment.
The first truck load of 8,000 bd' weighed 40,000 pounds.
Overall I feel blessed to be working with such a magnificent tree.
