Milestone #69 - Alconbury Mystery Cache

30ml tube

The cache is NOT at the milestone or the published coordinates. It is about a 10 minute walk away. You can drive about half way to the cache. At the half way point there is ample off road parking.

To find this cache you need to solve the following puzzle. I've given you 52 to start. Now you just need the rest...

30 + 28
20
51
7
10 + 11
48 - 50
26
62 - 28

You can check your answers for this puzzle on GeoChecker.com.

Due to this there will be NO hints. And as always - No Signey - No Smiley!
