The oil companies are to blame for high (but not sky high priices because they keep their profit margins as high as they can without upsetting the apple cart. You want to talk about sky high prices? Look to Europe, where a gallon of gas costs at least four or five dollars. Just had a neighbor come back from a trip to Germany and he said that gas goes for about eight bucks a gallon (if his math was correct). Cost him 76 dollars to fill the tank on his rental car.
