Cape Cod officials warn of white sharks ahead of July FourthCape Cod's beaches and towns may be quieter because of the coronavirus pandemic, but officials are reminding visitors ahead of the July Fourth holiday that the famous Massachusetts destination remains a popular getaway for other summertime travelers: great white sharks. Cape Cod National Seashore Chief Ranger Leslie Reynolds warned at a news conference that the powerful predators are coming close enough to shore to be a concern for swimmers. Officials in Orleans also have documented at least two shark attacks on seals in recent days, the Cape Cod Times reports.
