That is true kelkat - and reminds me of a lady down the street who always admired my pond and then invited me over one day to see her new pond. Now, I know everyone has different tastes, but her pond - to me - was ridiculous. It was a perfect 3 foot round circle ringed with rocks (like a fire-pit) in the middle of her vast yard.
That is all fine and good if she were going for a more formal look, but she kept going on about how NATURAL it looked. It looked as natural as a bucket.
