A swimmer from Danville is trying to do something that's never been done by another woman from the United States. During the last week of July, April Warrick will attempt to swim the Bonifacio Channel, which is 9.3 mile open-water swim from Sardinia, Italy to Corsica, France. Our news partner Newswatch 16 spoke to Warrick at the Danville Area Community Center where she trains. It's a swim April says less than a dozen people have finished. She was introduced to open-water swimming last summer. Since then, April has swam from Alcatraz Island to San Francisco twice.
