Hi all -

"plutonians"? I think not - pluton has a well defined
geological (planetary) usage. "plutos", with Pluto
being the first of the class, and no new word to
remember, just add "s" and make the "P" a "p" -

easy enough, and clyde'ss friends can't be too upset
with it -

Hopefully this will all be over by thursday, for the
time being... and we can get back to the formation of
meteorite parent bodies, hunting, dealing, pricing...
damn, I'm almost ready for another add from Chicago...
and whatever happened to Michael Casper, who
liquidated his holdings right before the torrent from
NWA flooded the market, while telling us all he was
going out of the dealing business for personal
reasons? cagey, wasn't he?

good hunting,
Ed
