Just seen the addition of The Sand Pits on the website.  I am enclosing a photo of a flood that occurred at the point where the Sandpits becomes The Parade.

On the back of the photo has been written "The flood. Parade. 1st July 1952.

I should imagine it was more probably caused by a broken main than a deluge... although you never know?

Cheval Meat Stores, 1948

Summerhill Home, 1962

Sandpits, 1953
