It is race weekend in Indiana. The 103rd Running of the Indianapolis 500 is Sunday and the Snake Pit, an area once known for its rowdiness and Woodstock-like atmosphere, continues its resurgence with a focus on nonstop music and partying. The new iteration of the event, which features some of the top Electronic Dance Music performers, has been embraced by the Indianapolis Motor Speedway as a way to attract fans and turn them into regular Indy 500 ticket buyers.
