MADISON — A program that pairs science and technology education with car racing hit the track at World Wide Technology Raceway on Thursday.

For the first time, the track invited youth teams from school districts and after-school programs throughout the St. Louis region to build and race their own go-karts ahead of the Bommarito Automotive Group 500 IndyCar race on Saturday.
