Bring sunscreen and an umbrella. Take out all your sound equipment- it adds weight and may bounce around in your trunk. Bring lots and lots of bottled water!
And yes, have fun, but keep in mind the things I said in my first post, give you an edge. If there are no foci there, ride along with anyone in a FWD car who's not in your class. Some people in your same class may not give the best advice (some people are petty about competition). Also make sure to put a large "N" on your car after your allotted number, so you can get first in the Novice class! You only get to be a "N" once! (E.g: 75 STS-N)
