Knoxville Raceway has decided when it begins its weekly racing season, it will do so with fans in the stands and not behind closed doors.  The races scheduled for May 16 and 23 will be moved to September 25 and 26.  Any other races affected by the limits on public gatherings will be cancelled.  Raceway officials say the Brownell’s Big Guns Bash with the World of Outlaws set for June 12 and 13 will be held with or without spectators, depending on the state guidelines in effect at that time.
