The tsunami of punting that they call Cheltenham
The horse was called Good Prospect, running at Cheltenham in the days when I'd have to cycle to one of the bookmakers in Athlone on my way from school, to place a bet. Good Prospect was 10/1, and it won.
It must have been quite a struggle to place that bet, because my clear memory is that I was in bed with the 'flu, listening to the commentary of Peter Bromley on a crackly transistor radio tuned into the faint signal of BBC Radio 2. So I must have dragged myself in to school that morning - not to go to school as such, but to be able to drop in to the turf accountant later, and then to get back home for Cheltenham, my business done.
Close readers might also be wondering if I had to negotiate any controversies with said turf accountant around the issue of my being significantly and obviously underage - to which I say, no, the matter was never raised and frankly, I'm surprised that you ask.
