Travis,
Saw you message.  I was working on this but i'll let Ira followup on this
one.
I recently left NU and now am working on environmental remediation efforts.
Th, U, and Ra are now my buddies.  I, working for a small company in CT
called Cabrera Services Inc.  (no not Canberra!).

The new job is fun and I'm learning new things all the time.  I do miss the
NEI task force group however.  Best to them all when you see them.
Hopefully we can hook up at the annual meeting.

Have a wondeful transition into the year 2000 and pseudo millennium.  Best
to your family and keep in touch.  My tele is (860) 289-1885 ext 18.

Hank Siegrist
