Serpentine rowing

More nostalgia from Pathe News, this time from sunsoaked summer days in 1950. These clips were rejects from a documentary called This is Britain, and show rowers on the Serpentine lake in Hyde Park. The boats look much the same today, but the film also shows hordes of swimmers and a diving platform, which is definitely no longer there. Far too dangerous (if you are a council apparatchik, that is).
Notice how the girl does what girls always do when being rowed on a sunny day by a pleasant young chap - she trails her finger in the water. Must mean something....
