The coordinates given are NOT where the cache is located. It has been placed within 3 miles of it. The coordinates provided are for a local supermarket.
The Puzzle
The coordinates for the cache are N50 51.OTT W000 12.FFS
The idea for the cache came from hearing a question at the weekly quiz down at my local pub. Later, the internet showed that Portslade was the nearest location where a cache could be hidden.
The Warning
I have received feedback that Ground Zero has become popular with dog walkers so beware the dog pooh / dog bags
