National Sprint Tour

After the death of Fred Brownfield, the series was bought by Don Lamberti and Lonnie Parsons (#6 Casey's General Store), Guy Stockbridge (#14 Elite Racing), and Steve Kinser (#11 Quaker State).

Boundless stated their goal was to consolidate dirt track racing of all classes to provide consistent rule and equipment standards and to create a national platform for this popular grass roots sport.

Noted driver Danny Lasoski mentioned the lack of media coverage since MTV's mistreatment of the World of Outlaws (see American Speed Association).

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.

Prominent drivers Danny Lasoski and Steve Kinser announced that they would be racing full time with the World of Outlaws beginning with the 2007 season.
