There was a guy in a state near me who got busted with 287 plants, 5 rooms worth of equipment; why? because he threatened a couple who didnt pay for the weed he sold em' said he was gonna kill them over $300, the couple told the cops (about the threat, they didn't know he grew) and whoaalla! The fear of helicopter detection is small, he was busted for being an idiot! helicopters are for chasing criminals, not invading peoples privacy block by block.
