I would ask that you don't give any hints or clues in your logs; no matter how obscure. One person's idea of being cryptic is another person's blindingly obvious.
When solving any of the clues below you can safely assume two things:
If your answer is 10, then actually take it to be zero.
It is possible that the same digit might be obtained from more than one clue.
So... You'll find the cache where lawns grow plush in the hinterlands, where there are many, many sheep and where none of the girls have such foul tongues. Or to be more precise at:
N51
God, you'll be laughing
your leading exports
see similarity
it's my department
I bring home the bacon
E 000
til the lights grow dim
what is the real thing
there you got your Rockefeller
and eat it myself
chit-chat, and clinking glass
Once you've found the cache you might need a little help to open it. What is the date at N000 00 000 E 000 00 000 (MDD)
