The cache is not where it says - going there would be troube for you from the propery owners.
You need to work out the coordinates from the puzzle below.
My Guy Fawkes Nights were spent at my grand parent's yard. They had a paddock where we would meet with our aunts and uncles and cousins for a family BBQ and then "Cracker Night"
I was lucky. My parents owned a Four-Square Store which sold fireworks. If there were any left at the end of trade, they were there for us to use for our Cracker Night.
The Catherine Wheel pictured below was one of my favourites as there were not too many bangs.
They would just go round and round, whizzing and whirring providing many showers of golden sparks.
To find the cache coordinates you need to decipher just the decimal parts.
