A photo of a huge alligator is making the rounds on Facebook and stirring all sorts of fears about what might be lurking in local waters. Reports suggest the gator, found on the shores of Lake Moultrie in Pinopolis, S.C., is estimated to weigh 800 pounds and measure 12 feet in length. It could have been 50 to 60 years old.
