Driving, as I often do, toward the Montauk Highway in Bridgehampton, crossing the place where Lumber Lane and the Bridgehampton-Sag Harbor Turnpike conjoin and a driveway for a large parking lot to the west butts in, I can’t help feeling a sense of satisfaction when I see the imposing 19th-century buildings that mark two corners of the intersection. Not too long ago they were in need of various degrees of rehabilitation and faced uncertain futures.
