The cache requires you to walk around the beautiful nature reserve of Hackhurst Downs, which has lovely views.
You should already have gone to Hackhurst Hack: View (GC11TY6). This cache was archived before I could fix it.
There is also a question to answer. What's buried there? The answer is a 7-letter word (and I'm not referring to the cache). Add up the number values of the letters in the 7-letter word (using A=1, B=2 etc). This should give you a final 2-digit number, km.
Also take the lower of the 2 telephone numbers you collected on the way to Hackhurst Hack: View. Discard the first zero and then you have a 10-digit number.
Each digit is represented by the letters below: npqrstuvwx
The cache is hidden at: N 51 13.(p-n)(r+s)(u-t) W 000 26.(v-1)(w-1)(k-1)
Please replace the cache exactly as you found it and make sure the lid is on firmly. I hope you enjoy the series and the walk. As the name implies you can often see cattle near to the cache. They are behind fences though, for those who are bovinophobic.
