Folks in Alaska are used to wildlife. (A story is that the air traffic controller at the Anchorage airport once told a taxiing pilot, "Bear left at the taxiway," and the pilot replied, "I see him.") But waking up to find a 500-lb grizzly (more properly, brown) bear killing an adult moose in the driveway. The Lyons of Homer, Alaska, found just that. This entry on Cryptomundo links to the videos the witnesses posted on the Internet.
