tw - The guy doing the Amazon marathon swim is a Slovenian .. and he's nearly there. He started Feb 1st, and is only a few days away from finishing. I thought he was swimming in a towed cage .. but apparently he's only using a heavy duty wetsuit ..
His website is high tech, and full of pics and videos ..
