I did! This looks like a hell of a great time!
I was surprised to read about all of the debauchery that goes on during this series. It's like a rock concert: Woodstock with horse-racing, only people dress better.
I've been to Saratoga several times; that's a fantastic track, too. Many folks, although a clear minority, dress up, with women wearing nice dresses and big hats. The environment at Saratoga appears to be rather stoic compared to Melbourne, however.
Glad you had a good day at the track!
