A terrified 15-year-old girl clung to a tree over a Florida lake, an alligator hissing below, as her mother frantically called 911 for help. "My daughter is stuck in a frickin' tree and there are gators surrounding her. We can't get her out. She's just 15," the mom cries. "Oh my God. Please hurry! Please hurry!" The girl had been rafting in Freak Creek during a family outing when she noticed a gator following her in the water, according to the Lake County Sheriff's Office.
