If you have watched the movie before, pay attention to where Homer asks Marge "How much money do we have left?", and Marge replies "Ten Dollars"...Homer gets all excited, and tries to ride the motorcycle, and fails 3 times...yet is given a "Free Ride", and wins the Truck, and The Simpsons are "Off to Alaska"...Okay...If they used the last TEN dollars to win the truck, then where did they get enough money for gas to make it to Alaska?
