Just a comment. A beautiful place about 1 1/2 hour North of NYC still has
chestnuts growing and proliferating. Unfortunately, they are susceptible
to the fungus and die before getting more than about 3 inches in diameter.
One hopes that somehow nature and Darwin will yield a truly resistant
variant of the species.

As a promising note, there is at least one in VA that VPI (Va Tech,
Blacksburg) researchers have been following for over 30 years now. The
precise location is a well-guarded secret in order to protect it (how
sad a commentary, unfortunately) but it has (at least last I knew which
is getting to be a fair number of years now) so far withstood the ravages.
