What to do while your car is having its MOT : go set a small series of puzzle caches. There are seven caches which will be published in the near future. The six decent sized caches contain bonus information for an eighth cache. Some caches are near roads - beware of animal holes; some caches are away from roads - boots recommended.
This cache is a magnetic 2ml tube. It is not at the published coordinates.
N52 09.xxx W000 29.xxx can be assumed.
From 55.9885°N 3.6827°W to 55.8699°N 3.6477°W
From 54.6639°N 2.7524°W to 54.2672°N 2.9669°W
You can validate your puzzle solution with certitude.
