On a few forums we had discussions about deadwood on broadleaved deciduous trees, also about big holes in trunks. We also had discussions about very good vs. lousy material. Here is a field maple (syn. hedge maple) which lost major branches after it was collected and finally was just a very big ugly stump. Twenty years ago I had this stump sitting in the dog part of my garden. A few friends came. One was not aware that i heard them when he said to the group 'I really wonder why Walter would keep this junk. This definitely will never be a bonsai'. Well, that's exactly what it takes to make me move. I love to do impossible things. Enjoy.
