In my purging, I also found a newspaper clipping from November, 1987.
THAT was pulled out of Lake Washington, in Seattle. (Sorry, the quality isn't very good.)
It's a 900# female sturgeon (found dead), that had about 100# of caviar inside her. They think it probably died of old age, and they can live 100 years. Yah.
But, swimmers, fear not. They're bottom feeders. Still... I wouldn't want that thing brushing up against my legs!
