Tsunami 'ghost ship' creeps toward Canadian shores

​It's been more than a year since the tragic tsunami in Japan, but a boat that was swept out to sea is still afloat and has been spotted by Canadian air patrol. There was no one aboard the squid-fishing boat when the tsunami washed it back into the Pacific, and now the empty "ghost ship" is drifting within range of other vessels. While one expert doubted anyone would try to tow the ship because of the expense, there may be some appreciation for so sea-worthy a vessel. It will likely get to land anyway: The ship and 20 million tons of other debris are plotting an inexorable course toward North American shores.
