I remember those too, but there was an air raid shelter at the school. I had to pass it on the way to and from school. I also remember the air raid shelters on Warstock Road. My aunt lived in Grendon Road and they were on the grassy strip in between the road and the houses on the way down toward Grendon Road. I left when I was 7, but still remember lots of things, I have a good memory.
When I was at my cousin's house one day, talk turned to school days, and my cousin's Aunty Cath. I remember her house as being very strange, sort of like a hut. That was on the going towards the church - is it School Lane? Aunty Cath was (and still is) a lovely, outgoing lady, and she did not 'fit' with her house at all. I don't know if you remember where I mean, but when my cousin produced a photograph, I was quite shocked, because it WAS more or less a hut! I think chalet was what it was called, but it was made of wood. That's the war for you, I suppose.
