Drug Enforcement Agency (DEA) agents staged a raid Thursday on a marijuana farm in Sanger, Calif., just outside of Fresno, and were stunned to find that the operation had grown to cover more than 50 acres.

In this helicopter footage, you can really get a bird's eye view of just how much marijuana was being produced here, although it's unclear if every last plant shown is the straight dope or other plants used to disguise the crop.

About 50 people were arrested, according to The Sacramento Bee.
