This series replaces my Unity in Confusion series where all the caches had the same name and you had to juggle multi, mystery and traditional caches all at the same time. This is much more straightforward series of 19 caches and takes in almost the same pleasant 5 mile walk.
It will be muddy unless we are in a drought at the time. There is parking for 2 cars at the parking place.
It is advisable to have a map on your phone/GPS and do the caches in order to minimise backtracking.
This is the bonus cache which can be found if you spot the NFC tag left in one of the caches.
Here is a picture of the tag with an AA battery for scale.

You will need a smart phone to read the tag. Most android phones and iPhones X and above just need NFC switched on in settings to read the tag while others need an NFC reader which can be downloaded for free. Touch the top back of the phone to the tag to get the coordinates. The process uses about 13MB of data.
After finding the cache, you can return to the parking place by following the boundary of the field as the farmer has decided to plant crops over the real path.
