They go surfing on Lake Superior.

Seriously.

This video was shot on Dec. 30, when it was minus-13 degrees in Duluth, and the lunatics in it decided to surf the break nearby at Stoney Point – which it supposedly one of the best places to surf year-round anywhere on the Great Lakes.

Go figure.

It’s minus-13. They’re surfing. Somehow nobody is concerned about frostbite or hypothermia.
