Beats me. I'm (now) on the committee but knew nothing about this.
Well actually that's not strictly true because I can hazard a guess at why the prize money is no longer available, but I'm afraid I can't say. What I can say is that if I'm right it will be much bigger than 9 people getting a few quid.
Bear in mind that prize money racing only attracts those with a realistic chance of winning
so means little to the rest of us.
Also remember that Woody won the 4wd series, so he's one of the people not getting £100!
