There doesn't seem to be anyone who can see the entire picture when these ideas come up. I was working in a couple of feed plants when they decreed that gasoline had to be mixed with ethanol. The price of corn (the base ingredient) got so high that the companies had to substitute other grains for it in the feed mixes. And since corn needs a lot of nitrogen to grow, the price of urea and anhydrous ammonia went way up, which of course affected all crops.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
