The NBC5/WPTV shark story that's getting all that attention

Click title for link to the NBC5 story about sharks off the waters of Palm Beach County. Here is an excerpt from the text of the story on the WPTV site:

     According to the Florida Fish and Wildlife Conservation Commission, sharks typically move inshore and north in the spring and summer.
     When Chopper 5 headed south along our shoreline Wednesday, it spotted hundreds of sharks, very close to shore, just off the northern part of Singer Island.
     Experts say many sharks are headed north after coming south for the winter to find warmer waters.
     Beach visitors need to be on the lookout for lifeguards flying purple flags for dangerous marine life. [emphasis added]
     However, it's important to note that you are 30 times more likely to be struck by lightning in Florida than attacked by a shark, according to FWC.
