The Out of the Groove YouTube chatroom was abuzz as fans attempted to guess the identity of the mystery driver. Jimmie Johnson, Tobias Forge (lead singer of the band Ghost), Dale Jr., Danica Patrick were some of the hundreds of names people flooded the board with during the race. There was only one Mystery Driver and it was Xfinity Series driver Josh Berry, who Eric revealed as the Mystery Driver of the Halloween Machine midway through the race.
