After being rained out last week, the Knoxville Raceway will have practice night tonight, the day before opening night at the Raceway. Practice night is used for many of the weekly drivers to test their equipment and shake down new cars and motors. For many of the drivers, tonight is the very first time their car will turn any laps this season. Tomorrow’s opening night is also expected to draw a few of the A-S-C-S 360 National drivers as they have an open weekend on the schedule. Practice night gets underway tonight at seven, and is free and open to the public.
