Just got the call as it happened, they can’t win for nothin with the weather!!
They had several new cars there too. Yes, it was raining at 6:30, but they should have hung in there a little longer before cancelling.
How was the crowd and the car count in the pits? Most tracks on a rainy night or a night that has rain in the forecast use that as the measuring stick as to whether to call off the races or not. It simply boils down to a matter of $ and cents.
