The color of marijuana plants is quite distinctive, but that doesn't mean it's easy to spot it from the air. You have to be down at a fairly low altitude just to pick it out, and the lower you are, the narrower your field of view. Have any of you guys ever been up in a helicopter? The ground is just fucking huge, and you can only see a tiny part of it at any given time. If you keep your grows small (a half dozen or dozen plants at the most), and scattered at random instead of planted in rows or some other telltale pattern, the only way a pilot could possibly spot it is just by the pure, blind luck of happening to look in exactly the right spot at exactly the right split second as he flies over at 50 miles per hour. And even then, the chances that he'd actually waste any time or fuel doing anything about a half dozen plants is even more miniscule. My primary grow area is a 20 to 25-square mile wilderness, and I see planes and helicopters flying over it all the time. I don't worry about it in the least. It's the guys on the ground who concern me.
