"Carl's Corner, Texas, is a truck stop between Dallas and Waco, Texas, where a little revolution has begun. Where truckers fill up on American fuel made from farm crops. BioWillie, they call it, because Willie Nelson is the driving force behind this biodiesel vision. His tour bus runs on it, (so do Bonnie Raitt's and Neil Young's) and a brigade of 18-wheelers barreling down the nation's highways; a growing fleet of semis whose exhaust smells like French fries."
With its dancing frogs on top of the truck-stop sign, Carl's is a well-known landmark for motorists who travel Interstate 35 outside of Dallas. Owner Carl Cornelius bought the land in 1979 and incorporated the town in 1986 so he could sell alcohol in an otherwise dry part of Hill County. He's been mayor ever since."
