In each cache there is a bonus clue which will complete the co-ordinates for the bonus cache... There are 2 chances to find each number, so if you can't find one cache, don't worry, you have another chance to find that bonus number again. In 2 caches I've hidden clues which help you solve 'Oy Ref!!' too.
I've tried to place as many different types of caches, with a variety of containers and hides. The common theme is they should all be fun and will take you on a lovely walk to popular and not so popular areas of the fields around Billinge.
This bonus cache isn't at the posted co-ordinates, you will have to complete the Lake District series, collecting the clues along the way to complete the following co-ordinates:
N53 29.ABC
W002 42.DEF
Please bring a pen, tweezers and replace all caches as found... Have fun, take plenty of photos for the logs and please give me any feedback to help improve the series.
