They sure didn't, but i was down at Marblehead this weekend and there was still plenty of ice build up along the shore. Not sure how things looked on the upper lakes, but that is where most of the Great Lakes shipping originates from these days.

That's why those ports matter.
It's what percentage of countries have one that would matter.
