Enjoy a seat in the shade in Stanton Harcourt's historic village green. You're looking for a small clip-lock box secured with a pair of strong magnets.
When retrieving and returning the cache, please ensure the lid is closed fully and replace it as you found it (see hint if you're not sure where that is), with both magnets fully-engaged against the host object. Also, please use stealth: this area is overlooked by several houses and is a popular area for dog walking and games.
