As the ow/tr/driver smallest margin of victory? A dead heat.
As the ow/tr/driver largest margin of victory? I didn't look back, but I didn't hear anyone behind me.
A little story from fifty plus years ago.
I am a teenager racing at the fairs.
I go back to the barn bitching that I won, but that the judges put up the home town boy as the winner.
I bitch like a spoiled kid.
The next week the presiding judge (Orin Baker) comes up to me and says "young man I hear you think you won last week".
I say "I sure did. I was looking right back at Kenny James when we crossed the wire".
Mr Baker "That 's right. You beat Mr. James across the wire, but your horse didn't beat his horse across the wire".
Then he shows me the photo.
Kenny James is driving a big horse(King Selka) hooked way out at the end of the shafts.
I am driving a real small horse hooked in short.
So yes I beat the other driver, but his horse beat mine by a nose.
I have never argued with any results since!
