Hudson River swimmer deals with fatigue, choppy water, rocks and pollution across 315 miles

Lewis Pugh is about to finish swimming all of it. After countless crawl strokes, Pugh has powered through fatigue and sore shoulders. “There is no other river in the whole world where at the source, you’ve got beavers, you’ve got bears, you've got vultures,” Pugh told The Associated Press before a leg of his swim recently.
