unpublished works

[wolffhound79]

I had a conversation with Pual Riegel some months ago discussing Ohio. He had informed me that there was a 3rd part to his twilight 2000 adventure for Ohio that was never published. I know there was the kenyan area and the seminoles stuff. My question is has anyone else ever come across or found information that was never published by some of the original authors of either challenge magazine or twilight v1 or v2 ?
