John Morton brought Datsuns and Nissans to podiums across the U.S. for decades. With this year's featured marque being Nissan, we're pleased to have him as our 2018 Mitty grand marshal. Want to have a quick chat and maybe ask him to sign a piece of memorabilia? Come by the big Classic Motorsports tent in the fan zone at 6:30 p.m. on Saturday for the autograph session.
