Congratulations to Samurai Sword on being FTF this cache (twice!).
This cache was setup to replace the now archived Old Bedford Road, if you found its predeccessor then you are looking for a different container.
Both the Old Mill (now a house) and the Mighty Sandy Heath Transmitter can be seen from the path leading to the cache. A circular walk from either parking place can be made taking in Old Bedford Road, Deepdale and Mill Lane, if you have mini-cachers with you, there is a playpark on Mill Lane.
