It's half as old as the Indianapolis 500, but the city's month-long celebration leading up to the race is exciting in itself Last year, more than 500,000 people participated in 500 Festival events that ranged from the Mini-Marathon to the parade. Just as many are expected for the first 2010 version event, a kickoff which begins at noon today with a free rally at Monument Circle in Downtown Indianapolis. http://www.indystar.com/article/201...ts01/Hundreds-kick-off-500-Festival-on-Circle
