Agree,the Promoters do what they think is best for their situation,but nowadays the riders don't want to ride if the track is wet and fans turning up with rain or rain sodden track normally have to hang about while "discussions are going on with REF" and that usually results in no racing 9 times out of 10 these days,hence fans reluctant to make effort ( only my opinion)and contributes to below average crowds when this happens.
