Norbert and others,

Congratulations to Norbert on his finds and the wonderful article about his
awesome lunar collection. Maybe your next article could be on your adventures
in Oman.

Not only is Norbert a lunatic, but he also has a bit of gabbro-itis, or the
love of our earthly gabbros. They may not be the same as a lunar olivine
gabbro like NWA 773, but such gabbros from earth are certainly some our close
cousins to it and other planetary material. I'm proud to say that Norbert has
some of my own finds of 1 billion plus year old gabbros from my collecting
here in Pennsylvania. My case of gabbro-itis is beyond help.

Norbert, we look forward to your next adventure and article. You are too
modest about your finds as Adam has suggested. A lunar find is a goal for all
us meteorite collectors and rockhounds.

John
