Great news re. Northampton. Hopefully, it's the shot in the arm that British Speedway needs and fingers crossed re. the return of Coventry, Peterborough, Swindon etc. Plus the fact it seems to be quite feasible that Northampton could host bigger meetings in the future considering the facilities there, Midlands location etc.
Various other sports have been on the decline in the past but they pick themselves up through a variety of different reasons (new innovations, sponsorship deals, TV deals, change of public perception etc.) and get back on track. Quite possibly and with fingers tightly crossed, just maybe it is now Speedway's turn.
