[Rockhounds] when volcanoes drop bombs: giant crystal payload

[pmodreski at aol.com]

Kitty, I have to admit, it wasn't the spell checker, I think I did that myself--realized it after I'd sent the email.? To AXEL, I apologize, sir.? Here I've been calling Kreigh, Keith, and Axel, Alex (well, the one is just an anagram for the other).? 

Who knows whose name I'll mess up the next time, Katy!???? : )

Sincerely, Pete (or is it Paul?)


Agreed, cool stories.?
?
BTW, Pete you should override your spellchecker so it will leave Mr. Emmermann's given name as Axel, not Alex! ;)?
?
Aloha,Kitty?
