You just have to look at the Poole v Somerset thread for your answer tbh. This morning calling for it to be off, then it was called off, now they are crying, forecast has changed so perhaps wrong to call off. By their very nature, it would appear speedway fans are weird. If a promoter calls off early, you will have conspiracy theories winging about, and if they try to get it on, but get defeated by the weather, they get it in the neck for putting money before fans.
Can't win, springs to mind
