That's apparently the moulted skin of a snake. An enormously large snake. A snake that was last spotted munching on a large mammal, possibly a beaver. That was back in June. But now comes this picture from over the weekend, indicating it's still hanging around.
The townsfolk in Westbrook, Maine, are fascinated. They've given the 10-foot-long reptile a name, Wessie. But until cops can figure out what kind of snake they're dealing with here -- a python? a boa constrictor? -- they're warning residents to keep a safe distance.
