This series features four traditional caches (roughly) on the perimeter of Preston. There's also a mystery cache in a central location that you find by collecting clues from each of the four traditional caches - located at points in the North, East, South & West of the city. This series was originally supposed to be something much grander, but it became difficult to find areas to place caches in the places I had hoped to put them. Find each of the four traditional caches (North, East, South & West), collecting the symbol written on the log. You’ll need that to complete the puzzle on the ‘Key to the City’ cache. Please get in touch if you have any problems and ensure you log a ‘Requires Maintenance’ entry if anything is missing or untoward.
A little hint... the South cache is closest to the Key to the City cache.
