Took my mom to the National Cryptologic Museum a decade or two ago. She still remembered it as the motel it had been when she worked translating Korean during that war, and got to have fun with "They've declassified this, now I can find out what they were doing, since we weren't cleared for it then"

Ha! Yes, the fact it's obviously a converted HoJo's is the best part

reminds me of that scene in The Bit Player where they interview Claude Shannon's ex-wife and ask what she thought when she found out Claude had been doing cryptanalysis during the war, and she just reacted with this look of astonishment and, after a moment, "well! I guess that explains a few things"
