Greg later left CDC (during the 1980's decline and fall) and went to 
Cray.  He was an active microcomputer addict and at the time, had a 
pretty elaborate Compupro system, IIRC.

I had the pleasure of introducing Greg to the wonders of gelato; I've 
lost contact with him over the years and am not aware of what he's up 
to.

His compatriot in crime at Arden Hills, Dave Callender (sp?) was 
quite a character in his own right. "Dr. Dave" maintained an active 
interest in bats and had various specimens on display in his office.  

Greg's work with MACE would not likely have attracted any notice at 
CDC were it not for Dave.

I was once told (but don't know if it's accurate) that he was a 
student of Harold Edgerton's and had suggested photographing bats 
using Edgerton's strobe--whence the great photos of the bats of 
Carlsbad Cavern originated.  Perhaps someone can confirm this.

Cheers,
Chuck
