Where were GPS co-ordinated when you needed them? I must have taken this photograph fifty years ago, when GPS co-ordinates were the stuff of science fiction. I am reduced to trying to remember where this abandoned lake was - and as far as I can remember it was one of the former boating lakes of Sunnyvale Pleasure Gardens at Hipperholme, near Halifax. If so, this was, at one time, one of the most popular resorts in Yorkshire that attracted thousands of visitors each day. How the mighty fell.
