Indianapolis Motor Speedway is expecting the highest attendance ever this year for the Indy 500. IMS President Doug Boles says he doesn't expect the race to sell out because they will continue to provide tickets.
Boles says the Speedway is responding to heightened security concerns much in the same way they did after the Boston Marathon tragedy. IMS officials say there will be more armed security officers on the grounds during the event. Boles says fans should try to get there as early as possible.
