Why three brothers are attempting a record-setting row across the Pacific Ocean

It’s a story of three brothers, a boat and thousands of miles of ocean. The Maclean brothers from Scotland are in the final stretch of their attempt to row nonstop across the Pacific from Peru to Australia. They’re going for more than a world record — they’re raising money for clean water projects in East Africa. John Yang spoke with the brothers when they were about 500 miles from Australia.
