CHICAGO -- A man from Chesterton, Indiana began his attempt at a record-setting 120-mile swim across Lake Michigan and back Thursday morning.
Scott Wolford, 51, expects the swim from Chicago's Oak Street Beach to St. Joseph, Michigan and back to take at least 70 hours.
Wolford is escorted by a support boat. To comply with open water swimming rules, he won't be able to be touched by anyone on the boat or hold on to the boat.
He will swim wearing only a bathing suit, a swim cap and goggles. Few people have successfully swam across Lake Michigan, but have done it on relay teams or wearing wetsuits.
He hopes to raise awareness of the importance of clean water, and to raise money for The Nature Conservancy programs.
