i agree about the muddy bottom. especially when it's covered in algae and it feels like youre walking on slime. eww gross. speaking of algae, i swam pretty much every day in a lake nearby this summer and then heard the lake was full of blue-green algae which can make you sick or get you killed. lol, disgusting. then again, i still prefer lake swimming over sea swimming, since lake swimming doesn't kill you. the sea is WAY too #$%#ing dangerous here. if you go out and you get caught by a underflow you are pretty much #$%#ed, you'll get carried out to open sea in seconds. and you can't swimg against the current, because then you'll die. happens to a lot of people every year.
