If you live anywhere near the Hamptons you probably have already made an appearance at the chicest horse show in the US if not the world. Now through September 2nd mingle with the rich and famous (not to mention the horses) at the most social show on the US circuit.
Did I mention also that it's uber competitive? You'll likely see Georgina Bloomberg and probably Jerry and Jessica Seinfeld's little one, among others. Go to the US Open by night and the Hampton Classic by day and you've got a perfect sports weekend!
The show has been around a long time!
Don't forget to pick up a shirt or two!
