Sad indeed.
Read one of his writings years back on whitewood bows and elm. It was in that writing he had said the oldest know bow recovered on earth was made of Elm of some type at that time. Remember him saying he had some Elm bows with over 10,000 shots threw them.
The post on his website is very well said.
RIP Dean, Your writing were as spry as you were in life.
