answer:I have a really good book (the title of which is escaping me but I will go look for it here in a sec). I really applaud your use of the tree in this way—many folks would just burn it! I decided to check Amazon to see if I recognized the book I liked. Didn’t see it, so I will go to the basement to look, but in the meantime here is one that got high marks that I haven’t seen and this one is specific to cedar.
