[Blue Marlin]

One of my favorite trivia questions among my harness racing friends is.
       Who was the first horse to break the 1:50 record for a mile in a race.
        Who was the trainer ? The driver ? The race ? 
         In the many years at cookouts or gatherings only two people came up with the correct answer off the top of there head. 

[Meadow Ford]

Well I tried.
All my answers came up with a
 "ya, but I don't think so."
So I had to look it up.
My guesses were all wrong.
I was not even in the right decade.
Hint
The right decade is the 80's

Yes Meadow Ford. It was in the 80’s. It’s one of my favorite trivia questions at horseman gatherings. I get all kind of different answers. There is the most frequent answer that most horseman go to.
