Dear Nancy, when I was there two things happened. Firstly the Police Divers pulled a mans body from the serpentine. This is nothing unusual as thou should not go swimming whilst drunk in cold water!
Then this attractive young lady did the ultimate no-no in a Royal Park, as she decided to sunbathe topless! That is a definite fine and removal from the Park, although I was a Gentleman and did not take a picture of her. Unlike a lot of other people, who seemed to be taking a lot of pictures of the said event!
If one wishes to go swimming Commando style, then at least do it in the dark!
Love.
Neil.
