Morning Edition’s Cathy Wurzer interviews Jim Dreyer, a 37-year-old man from Michigan, as he prepares to swim across Lake Superior. The 62-mile swim will start in Grand Portage, on Minnesota's North Shore, and end at the F.J. McLain State Park on Michigan's Upper Peninsula.
Dreyer has already swum the other four Great Lakes. If he makes it across Superior, he'll be the first person to swim a direct crossing of the lake.
