The underlying fear, that is fear of losing the tools we use because let's say a day of a electrical storm blots out the ability to have the computers working, the race venue running on just enough emergency power to keep the pies warm and the beer cold, (it happened one day at Cheltenham) and the bookies were still taking bets, they were "blind" to cos there was no tote screen.

If that was a scenario this Saturday, what are the options, what trump card would a punter have up their sleeve to get out in front and take advantage of the situation?

If one has a "trump card system", what would it be?

I was there at Cheltenham when the power blackout happened.
It was a day at the races that was rare in a sense, a rawness, no electricity, yet the races still went on and the bookies still took bets and the prices seemed to have a aura of good Value that day.
No one had a tote screen to look at.

Does anyone remember the days with no tote screen in the betting ring because the technology was not there at the time?

What "system" did the punter of that era have then?
