Ohhhhhh  Karen,

I remember that mess.  :(  Those roach critters took big enuff bites to make
me think it was rats!  Didn't we have problems in-house too?  Maybe those
runaway research mice got caught.  :)
Did they have a brand on them of  ~~B/T~~.   *Evil Grin*

I bet you recall those huge bags of blocks stored and it would take days to
find the one you wanted.  Glad to hear you were able to discard them all.

See you in May, maybe we should have a get together of all the people still
around in my hotel room at the Sheraton .  Plan to come visit the labs and
hopefully bring Steve Ott...remember him?
