In an effort to clear up the confusion, the IMS included a note with the ticket, which reads:
In 2005, legislation passed by Indiana's General Assembly and signed by the state's governor brings Daylight Savings Time to Indianapolis. So for the second year in a row, there will be a change in the local start time of the Indianapolis 500. Though your ticket was printed with a start time of Noon EST, the 90th running of the Indianapolis 500 will begin at 1 p.m. EDT (local time).
The IMS moved the start time of the race back an hour last year to accomodate viewers on the West Coast. If we're not mistaken, the IMS was among the many business proponents of the time change, particularly because of the live broadcasting of the event.
So what happened to an end to all of the time confusion we were supposed to get after the enactment of DST? Someone at the IMS probably got a good _ _ _ -chewing over this mistake.
