Basically, bring your driver's license (people actually show up without this sometimes!), your entry fee, and your car. Probably the most important thing you can do is clean out the car beforehand, and make sure anything loose is tied down tight -- batter, amplifiers, speakers...there's always someone trying to get through tech with a 5-lb amp in the rear footwell secured only by a couple of wires running to the rest of the sound system. We're not concerned if it's high-tech or pretty...I've seen batteries tied down with clothesline. As long as it works, it's OK. One guy showed up a couple months ago with a beer bottle serving as a coolant overflow tank...a hose clamp secured it to the frame. We passed it.

Definitely come out by 8, just so you can look around and talk to people -- ask for help, and you'll have as much advice as you can absorb.
