Camber Sands, England
(Another beach I spent an inordinate number of bliss-filled hours on when I was ......errm, "a bit younger than I am now", if you catch my drift!)
Irigny, France
(The only reason I've heard of this place is because when I was a holiday rep in the south of France, I had some "fun" one night with a lad who told me he was from Irigny. Can't remember his name, but can remember where he was from. Guess that speaks volumes!)
