This is number 2 in a series of 5 puzzle caches plus 1 bonus cache. The 5 puzzle caches in this series can be solved and logged individually. However there is a 2 digit number on the log book for all these caches and you will need all 5 numbers when you come to log the Pete's Puzzle Bonus cache.
The above co-ordinates are NOT for the cache. DO NOT go to these co-ordinates. The cache location can be found by solving the following puzzle: -
1 -7 16 -3 -9; 1 -3 18 -20 -33 x 1 8 -9 3 5; 0 1 0 4 2; 0 0 1 2 1; 0 0 0 1 -1; 0 0 0 0 1 = ?
You can take it that N 51 and E 000 are correct, the solution to the above will give you the rest of the co-ordinates.
Please take your own pen to sign the log
