As a teen in the mid-70s I worked at Hialeah Park. That was when it was a horse racing track. I was there for part of the winter season of 75, or 76? Around this same time of the year. Me and the outfit I worked for were from Belmont Racetrack in New York (trainer P.G. Johnson, number two in the standings at the time, now in the Racing Hall of Fame). It was weird spending Christmas in a tropical climate.
Did you make friends with the flamingos? I loved that beautiful track.
