Didn't claim this was a good solution. Come up with your own or be quiet. We don't need the thought police rushing to help us. The little bit of oil Marty uses or anyone else uses to stop weeds isn't the end of our planet... start at the top with Bush if you want to be a real help. Besides, Marty isn't going to use oil and has a much bigger job... and he did want NATURAL help, didn't he? Stay off this site if you're not trying to help or try be a policeman. Arrrh...
