If you have a scanner, bring one along with headphones. It's cool to hear some race strategy come out.

Be prepared for the dust the first couple of laps until the track gets cleared off. Sounds weird, but the first year it took me by surprise. I sit at the top of 1/2 so it may be worse there than other places, but just be ready for it.

Come early, lots of stuff going on and it's beneficial to get a good parking spot. Hotlaps at 5, which is mainly just a warmup session, and the first time the cars are on a full fuel load all week.

Other than that, it's the favorite race of mine all year. If I had to go to one race, and one race only per year, it would be the Little 500.
