I know a gent in his 90s who worked in the canneries on the coast. He has some stories to tell about the US military base near Prince Rupert. Apparently there was a large and very well equipped hospital that was bull-dozed and burned, complete with equipment in it.
He said something about the US base near Rupert having a reputation as being a popular hide-out for some scions who felt that was close enough to the sharp end for them.
