Getting to Anderson around 3 is perfect. They do a brief hot lap session around 4:30 or so, 1/2 the field at a time where everybody runs on full tanks of fuel and usually does a live practice pit stop. Buy some Little 500 or team merchandise before it sells out and hit the driver autograph session under the Pavillion. Grab a tenderloin sandwich from the turn 1 concession stand. Leave you ear protection off for the first 5 laps or so there is no other sound quite like it! Good advice on having the race monitor app on a phone or iPad and turn one seats are great as the sun sets behind you. Enjoy IMS and Kokomo!
