Oh man.. those suckers will swim right accross a lake. One day I was bass fishing and I look in the middle of the lake and see something. Could not tell what it was so I went out there. It was a white tail deer... swiming right accross the lake. I mean far... I stayed 25 feet from it and that thing kept right on swiming to a island, it walked up onto the small island, ran across it and jumped right back in and continued swiming to the shore. It dont suptise me to hear one drowned like that.
