We know zebra mussels spread quickly, but seeing them cover almost every inch of an object is astounding.
One North Dakota man apparently thought so, too.
He told Minnesota state conservation officers that he found a zebra mussel-covered shopping cart next to some dumpsters on the Duluth waterfront, according to a report from the Duluth News Tribune. He had put the cart in the back of his pickup truck and told the officers that he thought it would be cool to put on display at his hair salon.
Officers seized the cart and cited the man for unlawfully possessing or transporting a prohibited invasive species, the newspaper reports.
