The NASCAR Craftsman Truck Series races at Watkins Glen for the third time since 2000 this weekend (Fri., 5 p.m. ET, FS1).

Elton Sawyer, NASCAR's senior vice president of competition, joins SiriusXM NASCAR Radio to talk changes to the restart zone at Watkins Glen.

The last remaining asphalt short track in Colorado is located in Dacono, and it's thriving with a vibrant culture of racing.
