In the classic holiday movie “It’s A Wonderful Life,” Jimmy Stewart’s guardian angel showed him that he was the “richest man in town.” Ventura County Firefighter Greg Chavez’ “Guardian Angel” has made him a rich man, too. Chavez, a member of Ventura County Firefighters Local 1364, has won the nationally broadcast American Inventor contest – and a $1 million prize – for his holiday fire safety device disguised as a Christmas tree ornament. His “Guardian Angel” design beat out five other finalists and literally thousands of entries to with the contest, which aired on ABC television on Wednesday nights.
