Meet the Sodburys Bonus Cache
The cache is not at the given coordinates, which are at the Chipping Sodbury Clock Tower, home of the local Tourist Information Centre. This location is also the beginning of 'Meet the Sodburys' Adventure Lab, which you will need to complete to find the final coordinates for this Bonus cache.
You can visit Chipping Sodbury Tourist Information Centre for more on the town's historic past - currently closed due to Covid-19, so visit online at http://chippingsodburytic.co.uk/
There is also a heritage trail around the town, with a plaque to mark the start in Hatherall's Yard (see additional waypoint). Well worth it!
