Am I right to think that several of those bathing lakes are actually old open-cast coal workings? How deep and how cold are they?
after consulting my dad (i actually always wanted to ask the same question so cool you asked that just now) -they are either old coal, sand or pepple workings which were renaturised after the work was finished to be used by the public and wildlife again. i always wondered why they are called bagger see (digging lake).
sorry for the derivation of the thread




not knowing what was underneath you (I always remember those stories of people flushing their pet crocodile/snake etc down the toilet and have this completely irrational idea that some wierd animal/frond of green stuff is going to drag me down!.... 


) at the Serpentine and Hampstead. It's just not for me. As well as the irrational fear of what is swimming down below you, my technique involves taking in occasional mouthfuls of water.
