I knew the rain was bad when you could see ponds in the grass on the infield of the tri-oval, I know they well maintain that so if even that is saturated than the track has to be dismal. There really isn't anything they can do for Turn 1, the transition from banking to the flat side can't really be drained at all.
And honestly the number of yellow flags this year was more down to how many cars broke down in shitty spots. There were a lot more mechanical retirements this year than there was last year.
