Just come across a ticket I purchased in 1970 for a grandstand seat at Exeter Speedway - cost = 7 shillings (35 pence to the younger members of the forum!)
I know there are several ways of comparing prices from one age to another, but here's what one such site came up with:
According to the Office for National Statistics composite price index, today's prices in 2019 are 1,434.09% higher than average prices throughout 1970. The pound experienced an average inflation rate of 5.73% per year during this period.
In other words, £0.35 in 1970 is equivalent in purchasing power to about £5.37 in 2019, a difference of £5.02 over 49 years.
So, speedway shouldn't be a £10 sport, as some suggest, but something closer to £6!!!!
And if I remember rightly, it was a night of thrilling action at the banked County Ground circuit
