I totally dis-agree you should never cancel a race at noon because "chance of rain".Now if has rained or is raining that's a different story.Tracks that wait to the last minute to cancel get 5 or more races in a year then tracks that cancel on "chance of rain".I don't know how many times last year I got calls when I was at the track and the caller was saying it SHOULD BE raining there, the radar shows a red blob.
