I live 3-4 miles from the track and got 3.25 inches of rain Friday. My sister-in-law also lives in Springfield got 4.5 inches. Underpasses were flooded so badly that a 23 year old girl drowned when she got her car stuck, tried to push it out, and was sucked into a manhole, from which the cover got displaced, in the middle of an underpass .

Yes, we had some rain and no, I don't think there was any great conspiracy around the postponement/cancellation of the race. Just my opinion, I could always be wrong.
