Remember Jon Ornée, the athlete who swam the 7.4 miles from Pyramid Point to North Manitou Island in less than 3 hours last September? Tonight Ornée is pursuing another freshwater challenge. On Tuesday night, August 11, and into Wednesday, Aug. 12—under the Perseid meteor shower—Ornée and five friends are swimming 60 miles across Lake Michigan, from Two Rivers, Wisconsin, to Ludington, Michigan. They started their epic adventure at 7:15 p.m EST (6:15 in Wisconsin) and expect it to take 24-28 hours.
