Caernarfon and Perranporth do indeed make interesting "social studies"
At Caernarfon especially, most girls over 14 seem to be pregnant.
But they are lovely places to fly to - especially Caernarfon, flying over Snowdonia.
Shoreham beach is nice (I windsurf there) but is mostly pebbles. Brighton has a lot of culture and is just down the road.
