GCHQ?
Still recovering from my bout of stomach flue and nice to know I did not (as far as I know) tee anyone off. This on my little odyssey in 1956 across the highways.
Yep. GCHQ was my hometown's main employer. Out of politeness, I should mention to anyone who wonders what this is. General Communications Headquarters. The arm of surveillance, via radio signals in the cold war. Clandestine stuff. (chuckle).
And bet there are now a few who enjoyed their first exposure to signals intelligence.
Good luck with the flu!
