I love mamya's clue. My Dad was a GPO engineer seconded to work at Blethcley Park in the war. Of course it was years before he told us, and he finally got his medal the year before he died aged 90. Hope it is a wonderful day for your Dad
Hope you all have a wonderful day.
If you get the chance to be taken round by a gentleman called Hugh Davies, he's really good.
I'm afraid the "restuarant" is dreadful or it was last July.
