 From 2004-2006, when both Champ Car and IndyCar were holding races at the track, Champ Car still utilized the June date, while IndyCar chose to hold their race in late July.In 2007, when IndyCar became the lone open wheel race at the track, there was a renewed interest in placing the event on its traditional June date immediately after Indy.This arrangement lasted only three years (2007-2009), as the race was put on hiatus for 2010.
