the price of (used vegetable) oil in KY

From World, a blurb entitled "Yellow Gold"...

Rising energy and food prices have created a new niche for blue-collar thieves. For years, companies like Griffin Industries, a Kentucky-based agricultural-waste recycler, have been collecting grease from restaurants and selling the cooking byproduct to makers of alternative fuels like biodiesel. As energy and food prices soar, demand for grease grows, too. As a tradable commodity, its price has tripled in the past three years. And so petty thieves are now pilfering fast-food joints to steal fry grease. One man, David Richardson of Illinois, was caught by police allegedly filling up his tanker truck with used oil at a Burger King in Morgan Hill, Calif. A full tank of grease could be worth $7,000 on the open market.
