You guys that farm a lot are already aware of this I'm sure, but I was talking to one of my contractors yesterday and he was telling me they sprayed all their crops last year with a drone. Said the technology was awesome. All their fields were programmed into the gps and the drone would follow the correct path. The link below is not necessarily the one they used, but one that came up when I did a google search. He said it's the way of the future. Pretty cool in my book.
