Duluth, Minnesota isn't exactly known as the winter warm-weather capital of the USA. This video shows it's rather the opposite. It shows the giant barge Great Lakes Trader and her dedicated 'pusher' tug, Joyce L. Van Enkevort, entering Duluth harbor last Tuesday, December 13th, in a wind chill of -30°F. Just look at the ice buildup on her bow!
I'd say that's a tad chilly . . .
