Summer, where have you gone? Before trading in beach chairs for everything pumpkin, people hit the East End for one last hurrah and a slew of end-of-season events.

All eyes were on Bridgehampton on Grand Prix Sunday at Hampton Classic. Celebrities like Matt Lauer, Brooke Shields and David Cone mingled in the VIP Tent, where bottles of Wölffer wines and ciders were flowing and the table settings were picture perfect. When 2pm hit, the attention shifted to Grand Prix Ring as some of the world’s best riders and show horses competed in the $250,000 Hampton Classic Grand Prix presented by LONGINES. Karen Polle and With Wings were the big winners. Todd Minikus and Babalou 41 took second, and Chris Sorensen and Bobby were third.
