The last time I went to Blackgang Chine the cliff edge was gone so was some of the park I was like 12 so been a few decades or so
People have been saying this for decades.
There was a cool glass making factory that you could fill coloured sand still have my tiger full of sand when I was a nipper!
That's Alum Bay, not Blackgang.
Even had met a nice looking lass there 
Either you were quite drunk, or she was an import.
