I say if you've got it spend it!
Quoted from the article:
"The library has walls panelled in wood from butternut trees.
“It’s hard to get. That’s what we learned during the construction,” Mr. Bell says of the butternut."
Of course it's hard to get butternut wood! If it wasn't hard to get every hovel inhabited by the unwashed masses would be lined with it!
Excuse me now, I have to get back to my puppy mill.
