Haven't done it myself, but the photog at the link has a very sweet setup. He has a kayak type of boat, with a tripod type mount on it. And he can row around the lakes and rivers to get some awesome shots. I thought he had a photo of his setup on his Web site, but after looking around I don't see it. It is in his book, that I purchased from him, when I met him here in Meridian at an Art show.
