NEW CASTLE, Ind. -- Big Machine Records and Machine of Awesome were the co-winners of the Dan Wheldon Pro Am Karting Challenge, but the biggest winner, of course, was the Alzheimer's Association, which was the beneficiary of the $100,000 raised by the event's sponsors and participants.

Through multiple race segments and cool temperatures, our IMS and INDYCAR staff photographer Chris Owens was on hand to capture the excitement and thrills of grass-roots karting, all in the name of fun and fundraising.
