Mitchell was four years, one month, and five days old when he got his license. He may need a little boost getting into the driver���s seat, but once he���s behind the wheel, his car sure goes fast! Left turn, right turn, slow down for speed bumps ��� Mitchell is a pro. And he loves the way that horn sounds! There���s just one problem: Mitchell and his car have a slight disagreement about what type of fuel should go into the tank. . .
