1964 can be triangulated in a number of ways. Makes sense, and lends an air of credibility to the document. I realize it's yet to be proven authentic.
I read a few hundred posts from the newest posts, first, (tail end of the thread) and a few hundred posts from the beginning, last. The thread is moving at warp speed... hard to keep up.
Same here — everytime I go do something else I come back and I am way behind again. I didn’t read the center part either as it is moving so fast.
