Bonkers about Conkers

While having a scout around for possible places to put a cache, we discovered this large horse chestnut tree with some absolutely massive conkers. One of our ambassadors is absolutely bonkers about conkers, she collects them everywhere she goes and has piles of them round her house. If you're lucky, she wont have collected them all, can you find any? 

While you're here, why not also have a look for the cache?

The container is one commonly used for a cache, and it's in an area accessible to most people, but, be very careful of the river very close by. Swimming is not required!
