Always stayed in the free campground. The infield campground is usually sold out a year in advance but you can check. Visited some friends in the family campground outside turn 1. Seemed pretty nice. Not much hell raising going on. If I remember rightly, quiet time was 22:00. Bring lots of beer, or whatever you drink. They have honey-dipper trucks that come around to service the tanks. There are people coming through every couple hours with ice. Not exactly cheap but really convenient. Make sure you have everything you will need food and beverage wise. It is not a pleasant experience trying to drive into town to get something. By Sunday, rolls of toilet paper are worth their weight in gold. Bet you could pay for your trip if you brought enough of it. You will need comfy shoes and extra clothes in case it rains. Pretty much the same as any other camping trip. Scanner is nice to have but you can rent one there if you don't have one. You will need a hat for sure.
