Today's Carb Day festivities kick off what Indianapolis Motor Speedway President Doug Boles says has become a "must-attend weekend" for both hardcore and casual racing fans. Boles says almost 70 percent of the people that come to the Indy 500 don't watch another race all year, giving Indianapolis a unique opportunity among host cities to showcase itself. The Speedway has also released the logo for next year's race, which it says will be the basis for branding in future years.
