It has very little to do with format. Its the lack of publicity that has killed this sport. I remember, in the 90's I rediscovered the sport due to sitting in house near Powderhall, Edin, with the boys, hearing a noise, which I recognised & next week taking them. NOT because of any publicity, but because I recognised noise! During that time, even though Ed had been there for many tears, when talking to a good (all) friends all expressed surprised that "Speedway still existed"! In other words NO PUBLICITY.
If you don't know you don't go....
