You call that a Lake?

My brother took us driving around Louisiana on Sunday and so he drove by the "lake" by his house. Well me being from Kansas was used to a wide open area full of water, with no trees in it just people and boats and fish/turtles/snakes and whatever else grows in a lake. Louisiana however is mostly swamps, but this "lake" or so he called it had huge Cyprus trees growing in it. He told me that many people take boats out but ruin propellers like crazy hitting stumps they can't see underwater. I was amazed!
