So this couple built this very sophisticated pot farm underneath a house. It has hidden hydraulic door in the garage, an irrigation system, surveillance cameras everywhere and an escape route that goes out a door hidden under a fake rock. If I decided to build a pot farm, this is close to how I would do it (mine would include robots in medieval armor that poses as decoration until set off by motion sensors and attack the intruder). The story has lot of pictures of the pot farm and some guesses as to how they were caught.
The US Coast Guard made one of the biggest drug busts in history. They found 20 tons of cocaine in a port in California. The estimated street price is $300 million for frugle shoppers (wholesale) and $600 million for retards (retail).
