Newport Polo Club
250 Linden Ln., Portsmouth
Newport's polo club is the oldest in the country (founded in 1876), so it's no surprise that the grounds are a huge part of the appeal here; the original property was called Glen Farm, and was complete with an incredible stone barn and stable. There are matches every Saturday in the summer, and the tailgate is an important part of the scene–regulars will have huge spreads and tents, but all you need is a bottle of champagne, cheese, and a picnic blanket to take part. Elaborate Kentucky-Derby-style hats are highly encouraged.
