Demise
Fred Brownfield was killed in June 2006, and with the series future in question, its assets were sold in early July to three team owners in order to finish the 2006 season-- Don Lamberti and Lonnie Parsons (#6 Casey's General Store), Guy Stockbridge (#14 Elite Racing), and Steve Kinser (#11 Quaker State) for $250,000. Since Brownfield had only 2 months to put together a 2006 schedule, the schedule had only 45 dates.
There was intense speculation in October 2006 about the future of the series. The NST had not announced a racing schedule for 2007, and most of the prominent industry promoters decided to sanction World of Outlaws events. Prominent drivers Danny Lasoski and Steve Kinser announced that they would be racing full time with the World of Outlaw beginning with the 2007 season. The World of Outlaws announced it would be nationally broadcast on the Speed Channel and ESPN2 in 2007. NST announced over the 2006-2007 offseason that it would fold as a national tour, while selling its remaining Northwest-based tour, now the Northwest Sprint Challenge Series.
