About SideTracked Caches.
This cache belongs to the SideTracked series. It is not designed to take you to a magical place with a breath taking view. It's a distraction for the weary traveller, but anyone else can go and find it too. More Information can be found at https://www.sidetrackedseries.info
About the cache
One of two London Underground stations in Dagenham, this one is close to an emerging film studio, where scenes for the BBC series Luther and the Marvel film Dr Strange have been recorded. The parkland between Dagenham and Elm Park has a number of caches for those with a little time.
Congratulations to Tbear186 for the FTF :)
Rubber duckies were a very poor second. Try harder Matt!
