If you're out there in the witness protection program...good luck in the rest of your travels my friend.

Know that you were a valuable contributor to our little community/addiction.

If circumstances are of a more permanent nature...Rest In Peace, and know that you were held in high regard by your peers...Thank You Mr Griffin.
