I live in Fairbanks, Alaska. Up here there are literally 10's of
thousands of square miles of old growth black spruce forests. Really
slow growing, tight grained wood that HAS to be tougher'n HELL. I've
often wondered if there might be a market for it.

Those are also tiny little things covered with branches (read: knots).
I shudder at the thought of how many pieces you would have to scarf
together to make anything useable. Another reason why the old growth
sitka spruce and doug fir make good aircraft structure is fewer branches
on the lower part of the trunk, which is more likely to develop under a
high canopy.

Wood is a great building material and I've enjoyed using it to make a
couple boats. For my airplane I'd rather have all metal structure just
for the consistency of the material.
