This weekend, in case you hadn't noticed, is Halloween, the time of year you're guaranteed to hear about the supernatural and the scary. But in Central America and some parts of Texas there's an urban legend, a scary urban legend, that people have been talking about year-round. It's the tale of the chupacabras, or goat suckers. It was first reported in Puerto Rico in the mid-'90s, with stories of livestock being ravaged by a mysterious half-dog half-bat with - creature with gray scaly skin and no hair. Hmm, that's, yeah, that would be scary.
