dw, along those lines, GPS farming has happen so fast it amazes me. I read about it just a couple of years ago, and now most corporate farms use it. I was playing poker at a horse track with a farmer last spring on a rainy day. he said most all corporate farms were using it and service he can hire to do his, which he does. That, electric cars and driverless cars, geez science is maybe advancing too fast?
