During an underwater hunt not far from his seaside home in Mahone Bay, N.S., shipwreck diver Tony Sampson and his crewmates aboard a barge found "the mother lode" last week. But it wasn't treasure. It was another man's trash — abandoned or lost fishing equipment, called ghost gear. "Looming out of the darkness came these images, it almost looked like the Titanic," Sampson, who works for the company Titan Maritime, said with a chuckle.
