Only three cars showed up for this race.  Both car 5 and 85 were last minute drop outs because the driver/owners had to work this day.  Car 24 didn't show and didn't explain why.  Car 81 would have had a pretty good day except it had to drop out while leading three different race due to a mysterious slowly dropping oil pressure condition which forced them to pull off after 8 to 10 laps.
