This is a magnetic nano cache. I don't tend to do micro caches but Whitland is lacking in caches, so as this is in the town itself, be wary and use stealth.
It isn't too hard, just be careful of traffic within the town.
You may want to visit the Hywel Dda Centre which is just up the one way street, behind where the cache is placed.
Parking is available on the street or near train station.
Bring a pen!
