The engines will roar to life Saturday night at the Lucas Oil Knoxville Championship Series Cup Opener at the Knoxville Raceway. General Manager Brian Stickel says it’s going to be an exciting season. Stickel says there is no lack of talent in the field, and it’s anybody’s guess who will be champion in August. Saturday is also the first of four free kids’ nights, and a fundraiser for area schools and organizations. $5 of every $15 adult ticket purchased goes back to fans’ designated organizations.
