A cruise around the South Fork last Thursday revealed that about 99 percent of the deciduous tree leaves had fallen. The ground beneath the oaks, hickories, and other trees on either side of the roads in Northwest and Middle Line Highway and Old Sag Harbor Road in Bridgehampton were completely covered with brownish leaves from this year’s crop. The woods, per se, were as they should be, bare trees, underbrush, and a thick leaf groundcover.
