What do Minnesota, California and Hawaii have in common?
Although it's not the first thing that comes to mind when you think of Lake Superior, MPR reports the frigid waters can compare to the best surfing in the country.
At least 50 surfers in thick neoprene wetsuits gladly jumped from the rocky bay of the North Shore on a cold February day, as part of a thriving surf scene in northern Minnesota.
MPR has some great shots in their photo gallery.
The best surfing conditions come when winter storms kick up 35-mph winds, 15-foot waves and sub-zero temperatures.
