If you are going, refrain from using money on the site. Upon arrival, leave all your alcohol at the A-camp, so they won't have to pass the hat and go to town to buy beer. Be respectful while taking pictures of people, ask first if at all possible. Find out where the latrines are, or better yet help dig at least one. Learn how to trade for what you want or need, think of the experience as what would happen if our civilization were to fail and we still needed to function. Do help out at the various kitchens and communal campfires, such as gathering dead firewood from the forest. Learn some good jokes and stories to share. And when leaving bring out as many bags of garbage as you can fit in or on the car.
