You are looking for a container within a container. It is located between a concrete track and an old wall within the boundaries of Buckingham Park.
There is a logbook but no pen.
This is a bit of fun (hopefully). Well, l certainly enjoyed making it! The outer container is easy to open if you look carefully. PLEASE DO NOT TRY TO REMOVE THE INNER CONTAINER! Instead, use a key or something similar to remove the plastic cap. Please replace everything carefully.
Please use stealth in this often busy park and try to replace carefully.
Enjoy
