I believe the catalyst was when people like Ric Frost was driven out of the sport. He came in expecting others to uphold certain standards of decency and integrity , but instead he was IMO rubbed out by the Mafia. The standard of such person was to be told if you don't like F***off. We are seeing in some quarters a brief resurgence but I feel this is to be short lived.
We are now a third world nation Speedway wise when not so long ago we were top of the pile.
