Because, even if your figure of 50% (which I contest) is right - that still leaves 50% of Supporters were happy to watch the 'Second Halves' - I know I was. I know too that a lot of the time the Result of the Rider of the Night Final was arranged beforehand - but I still saw some terrific Races. Plus, as others have said, it was a great introduction to Speedway Racing for the Juniors.
I, for one, mourn the passing of the 'Second Halves'..
