The Arnold Motor Supply 360 Knoxville Nationals get started this at the Knoxville Raceway. General Manager Brian Stickel says they’re prepared for the thousands of guests they expect at the track this week. He tells KNIA/KRLS News that ticket sales are strong and they could see 10,000 people in the grandstand Saturday night. After the 360 Nationals run through Saturday, the Capitani Classic returns Sunday night. The Nationals Queen contest is Tuesday, and the Nationals run next week Wednesday-through-Saturday.
