Your destiny? McCall Idaho Winter Carnival 2012 Festival in Idaho's Winter Wonderland! Sharlie and all of us in McCall anxiously await your arrival. Sharlie (Slimy Slim, The Twilight Dragon of Payette Lake) is the name given to a reptile-like sea serpent much like the Loch Ness Monster that is believed by some to live in the deep alpine waters of Payette Lake near McCall, Idaho. The first reference to the sea serpent may be the belief of Native Americans, predating western settlement of the area, that an evil spirit dwelled in the lake. http://en.wikipedia.org/wiki/Sharlie
