In a certain small town in middle Georgia, 22 years ago, I watched in disbelief as a helicopter hovered over a very good friends grow in a field behind his house where he had nine 6-7' plants within days of harvest. For whatever reason they rappelled down from the chopper, cut the plants down, and found the trail going to his backyard from the grow. I guess that they were showing off. Not sure. They could have "walked" a patrol car into the cul de sac and they could have trotted right out to the plants. Needless to say, they obtained a search warrant for his house and found what they needed to nail him. Funny thing is, there were over a dozen more even bigger plants not even 50' away that they never saw, but we were too scared to go back to them being afraid that they DID see them and were watching them. Eventually I went out there at night, per my buddie's request, and got rid of them in case they came back after it was clear that they missed them.
