Cops in the Central Valley following a tip about a possible meth lab in Merced found something illegal, but quite different when they got to the scene.
The plants were in a corn field in various stages of growth, Sacramento-area TV station KCRA reported. The street value is about $478 million, authorites say.
It took 25 officers from several different law enforcement agencies to harvest the plants, which amounted to a pile 5-feet high. On Sunday, authorities burned the pile of plants.
