With hundreds of shark sightings this summer, enjoying the beach on Cape Cod is getting a little harder these days. A Portuguese Man-O-War sighting shut down Harding's Beach in Chatham for hours over the weekend. And now, numerous beaches in Yarmouth are shut down for some sightings. Acting Natural Resources director Bill Bonetti reminds local beachgoers of their painful and sometimes dangerous sting. He says the elements should hopefully carry the Man-O-Wars away in the next few days.
