I've been visiting the Oostvaarderplassen on a regular basis for more then 10 years now. It's a very interesting state park that changed a lot over these years, mostly due to over population I guess. And I mean over populated by nature, not by humans. You'll find a nice video of the area on YouTube: http://www.youtube.com/watch?v=v3tPkklklfU&feature=player_embedded#!
