NOEL KING, HOST:
Good morning. I'm Noel King. Over the weekend, 3,000 or so people biked through the streets of Philadelphia. They were advocating for rider safety, protesting dependence on fossil fuels and promoting a positive body image. That's a lot of causes. So how did they stand out? Well, many of them were naked. Philly's Naked Bike Ride is an annual event. Melanie and James O'Connor, who were riding nude for the seventh year in a row, told the AP, we run around naked a lot.
