Or maybe they thought it was only going to be a short light shower which wouldn't affect things!
In the past when rain has been properly forecast they tend to push the races through.
Given this is how it looked at 7pm last night did any of us really expect heavy rain less than 2 hours later? Hindsight is a wonderful thing.
Do we know that it is actually oil? No, all we know is a black coloured liquid has been poured onto the track. Lots of assumptions and very little facts.
Update on Jason from his Facebook page
Wow, given how nasty that crash looked he seems to be a very lucky man. Fingers crossed for a quick full recovery.
If you get there early you can park in the Stadium car park otherwise the town centre car parks are only a short walk away. The ones near the train station being the closest.
