Summer presses on, hot and humid with an occasional bout of rain. The beaches fill up on the weekend, the traffic is crazy mad on the South Fork’s main thoroughfares, County Road 39, Montauk Highway, Noyac Road, the Bridgehampton-Sag Harbor Turnpike, Route 114, and the Scuttlehole-Head of Ponds-7 Ponds-Mecox Roads, which wind through the fields of Bridgehampton and Water Mill and meet North Sea Road north of Southampton Village.
