it was and up the lane which if I remember rightly was called sandy lane was the other part of the works where they dug up and shipped the sand to the queslett road plant . old booths farm house that is no longer standing was also storage bay for blue circle cement . I know it all well has I was born and lived in Ashworth road there was a road between my house and the quarry . I loved the place, in my memory of how it all was i still do, it was my big front garden has a child . I used to wag school ( perry beeches and calshot little school ) over there it was super fun there was always lots of frogs and newts and stickle backs pike and roach in the lakes , a lot of people went fishing over there . In my mad teenage years I was with a bike gang called the mad mob it was our stomping ground and sorry to say although in them days was accepted as one of the scrambler clan that loved to ride there bikes over there . I had a montessa trials bike .. oooo the memories ..I do have some photos somewhere have to try and sort them out . Just ask I'm sure I could tell you lots about this wonderful place ...
