The pool at night at the Golden Nugget Hotel, complete with Shark Tank.
Taken using the Sony Nex 5 handheld twilight mode which fires 4 or 5 shots and merges them somehow to create the image.
Oooh... I thought you were going to tell us that this was where you had a night-time swim, but now on reading your note I realise that might be rather a foolhardy exploit in this pool!
