Relief as much as elation coursed through Scott Dixon's veins after claiming his second IndyCar Series crown in Chicago today.

He couldn't help but reflect as he wiped off the traditional cream pie that had been rammed in his face by Target Chip Ganassi teammate Dan Wheldon in the victory circle.  "The year on a whole has been amazing, an unforgettable year", said Dixon who also won the 2003 title.  "Getting married, winning the 500, winning a championship in one year - not too many people can probably say they have done that".
