I acknowledge your precedence in first noticing this, Mr. Parcher.
Something that further intrigues me, but is certainly no "smoking gun", is what Green writes on Page 116 of Apes Among Us:
"It was in the fall of that year, about six weeks after Rene and I had see the tracks on Blue Creek Mountain and a Bluff Creek Sandbar, that Roger and his friend Bob Gimlin went to Bluff Creek in Bob's truck and three horses, to look for Bigfoot. Roger had already taken a GREAT DEAL of 16 mm movie footage of outdoor scenes and other material to use in a show he planned about his hunt for the hairy giants, and he had a reasonable chance of getting some footage of Bigfoot tracks if he could stay with the search for even a few weeks." Emphasis mine on GREAT DEAL.
I know there has been speculation about the contents of the "second roll", but this passage would seem to suggest that Patterson took much more Bigfoot related footage than just two magic rolls. Are they still around? Who might own them? What is on them?
I suspect that if the advocates ever concede the "official version" of the plaster pour and cast display is bunk, then they will fall back on the "plaster pour" scene as coming from part of the "other material" that Green refers to.
Frankly, I think that this is what is really going on here, that Patterson shot lots of what we would now call "B roll" material, and that this is what is now mistakenly being claimed as being shot on Friday afternoon, Oct 20 1967.
