I just finished watching the last episode of a series called Islands of Britain. It was really interesting, and i thought you ought to know about some of the ones mentioned in this last episode. South of England there's a small island called Sark, which is the last feudal state around. All the farmers rent their land from the baron, and there's no cars or motor vehicles allowed on the island, except tractors (and that's only if you need them for work). It's a really interesting island.
Then there's bishop rock, allegedly the smallest island in the world, and the most south-westerly point in Britain. This picture speaks for itself - the only way to get there is by a small helicopter.
So there you have it. Something to have learnt for the day :)
