I also went power when we left the sea.
I had a good friend, now sadly passed. His family moved to the Chilterns to find work in the 1930s from Sunderland and he was born a Bucks Man. Money was tight as the only work was agricultural but they got a cottage and food was plentiful being grown and shot.(plenty of rabbit then)
In the 1950s he was called up for National Service and managed because of family history to join the Royal Navy. He did infact stay in and did a total of something like 26 years.
The thing is, there was no such thing as a family holiday. When he got on the train at High Wycombe to report for basic training he was 18, I think, and had never seen the sea!!
