I went over to race control for some black bin bags to put the tent in about an hour after the meeting was abandoned and seriously most of the track had standing water on it, not just odd puddles. There is no way any more rounds could have been run.
IMHO it was a good call, and thats not because I had a good result today, I still don't actually know where I finished with all the confusion!

I ran in heat 11 (of 12) and the track was dangerous to marshal, I half fell marshalling one car (much to everyones amusement)
