As the late summer sun sunk low in the sky, a flash mob of about 280 guests dressed all in white converged on a vacant lot on Main Street in Durham Sunday evening for An Evening In White, a fundraiser to benefit the United Churches of Durham and the local food pantry. The event was inspired by Diner en Blanc, which originated in Paris in 1988, according to Lisa Davenport, one of the organizers. Guests were instructed to bring their dinner, china, silverware, drinks and centerpieces and the organizers provided tables, chairs and table linens. The location was not disclosed until a few hours before the event, creating an air of spontaneity and excitement. FoxCT’s Tony Terzi served as master of ceremonies and live jazz was provided by the Jack Riotte Trio.
