Yet if you do an actual comparison of the tracks in operation in 1990 with the tracks in operation today, you will find:-
We have lost – Reading, Oxford, Bradford, Cradley Heath, Hackney, Wimbledon, Exeter, Long Eaton, Milton Keynes, and now sadly Coventry…. A total of 10 tracks.
But we have gained: Leicester, Somerset, Scunthorpe, Sheffield, Workington, Birmingham, Buxton, Isle of Wight, Kent, Mildenhall and Plymouth…. A total of 11 tracks.
So we actually have more stadia staging speedway in 2017 than we did in 1990.
