My taxi pulls to a stop in front of the Interlaken Inn in Lakeville, Connecticut, amid a small traffic jam of gleaming 911 Turbos, Panameras, and GT3s. A half dozen or so well-groomed men rush to open the hotel door for me—apparently women are in short supply at this gathering of the Porsche Club of America. Just three miles down the road is Lime Rock Park, one of the fastest road tracks in the country, and one of the most legendary. Mark Donohue made his name there, as did Mario Andretti’s grandson Marco. “You’re the first woman I’ve met to do this,” the receptionist tells me, noting that women drivers have yet to achieve equality on the racetrack.
