Sorry it took so long for this:
I've been going for about 10 years.
- Use the map provided on the ultra4 website, at the gate, or on Cartotracks.
- Camp wherever you can find room (there are a lot of people and most of the "best" spots will already be taken), ideally away from trails or you will be dusted out and up all night.
- Spectator areas: Hammertown jumbotron, Backdoor, Chocolate Thunder, (there will probably be a jumbotron at those two locations as well), turkey claw and Lasernut Alley (this is fairly new); again use provided map to find.
- If all else fails, follow a random group and see what you see; it's all good!
Have Fun!
