The two skeletons in Scotia might have been looking for rum, black pearls or pieces of eight. They settled for pieces of cookies. Mark Renaghan, 6, and Jamie Deyette, 6, were trick-or-treating in black-and-white costumes on Lincoln Avenue for Halloween 1982. The bone men found their treasure at Nancy Gifford’s place, and Nancy was glad to pass out homemade sweets and put some meat on the ribs of her visitors. Kids and adults will find time for the October traditions on Wednesday — Halloween 2012. Some will carve pumpkins and give the holiday a frightful face, the way Amy Rein of Scotia did in 1993.
