Dr. Ned Mamula barely touches on his book "Groundbreaking! America's Quest for Mineral Independence" which seems pretty darn affordable as a Kindle title. https://www.amazon.com/dp/1729669522
I'll be checking that out, as I'm the guy stammering out a question at the end about "Operation Dragon Bridge in Canada?"
(Said with the same inflection as Month Python and the Meaning of Life: "A Tiger? In Africa!?!")
Ned is chroma-keyed with a green JPG image projected from Karl Pauls's spare projector. That actually worked!
