with regards to the "mill" or "cock fighting ring" on Bidston Hill
when i was about 12 myself and my dad were wandering up there and came across this....it was very overgrown at the time, we were both intrigued so did a bit of research into it...when we found no hard evidence of its use we got the rangers permission ( Mr fox ?) to clear it....we did so , emptying the trough and centre pit.
We photographed, measured it all and drew up plans. We wrote up what info we had found and gave a copy to the rangers up there.
wonder if i still have a copy
