Your guess is as good as mine but the evidence is available for
all to see in some pictures I took of our findings in Colorado. These are now
in "Turn Left at the Pacific" - the book I've written about the whole event.
Within the next day or so, I'll be making an announcement on the lists as to
its availability and how to order a copy.
It's a big one - 316 pages, lots of
colour pix and the whole story in which the key players who developed and
executed the event have all had their say. If anyone on the list wants to know
more, send me an email off-list and I'll send a separate .pdf file with all
