what does it take to scratch a horse????

[wac]

So im all excited about drilling for oil in the 8th at CD and i watch in horror as the horse did just about everything but do a bucking bronco impersanation at the gate but they dont scratch him???? WTF i watched my money gone as soon as they open the gates of course horse runs like his tail is on fire for about 3/4 of the race and fades bad. What does a horse have to do to get scratched at the gate? If i ever wanted one to be scratched that was it.
