OK, a bit of fun today … tongue-in-cheek only … but still a real story.
Just off the North coast in the UK there exists a tiny little tidal island known as “Holy Island” and built upon it is the monastery of Lindisfarne. Recently it has become the centre for the revival of Celtic Christianity and so it has become a popular retreat centre, as well as holiday destination.
To get there there is a tidal causeway – hint: when the tide is high, you don’t cross. Ah but I don’t need to tell you that, its the bleeding obvious, yes? … right? … apparently not.
