American Idol auditions are being held at the Illinois State Fair this weekend.  Anyone between the ages of 15 and 28 can take a shot at making it big.  The celebrity judges won't be there though.  Officials say the show producers will screen talent and determine if they're eligible to move on to the next round of auditions, which will be held in another city.  Auditions are tomorrow and Saturday from 10 a.m. until 5 p.m. outside the carnival entrance.
