Hi Bathbiggles1.
First of all, thank you for your answer. I am looking forward to diving there, although I am a bit worried about sharks (and currents, of course). I have already dived with sharks in Roatán (Honduras), but it was a shark feeding and I was very calm; what scares me is meeting a shark face to face, I can´t imagine my reaction. Well, about the buoy, I always take it, I think it is a quite important thing.
Secondly, six o seven years ago, I visited Marlow and Little Marlow, near High Wicombe and Aylesbury (I don´t remember their names), and I liked them a lot. I remember the church in Little Marlow and a nice walk along the Thames.
Ok, thanks again. I will tell you something about Brothers when I go back, and... sorry for my English.
