Traffic on a highway in California came to a grinding halt after drivers stopped by to pick up hundreds of face masks strewn on the road. Some believe that they may have accidentally spilled from a truck, while others report that a man was spotted throwing boxes of the masks. The images were shared on social media by the California Highway Patrol, but they didn't confirm how the masks ended up there. It took almost an hour of cleaning and stopping the traffic to removed the masks from the road. After several countries made masks mandatory to fight Covid-19, they have become prized commodities with many reporting shortages.
