First time going to the track. Any advice?

Ask somebody who knows, which side of the track the turnoffs are, and how many. At my local track we have at least ten cars a night on test-n-tune night, doing u-turns on the track because they think they passed the return road. They apparently dont know there is another one, even though lots of fast cars dont use the first one. (Doing a u-turn on the track is a HUGE no-no!)
Also ,if you are gonna do a water burnout, pay attention to the track personnel! They will tell you when to go. Do NOT start your burnout with a car in front of you!
The rookies i see that crash their cars all do the same thing wrong. They'll leave the starting line spinning the crap out of their street tires till they get out of shape, correct for the sideways motion, take their foot out of the gas, and then the tires hook up and they drive straight into the wall. Dont be that guy. If you spin hard off the starting line , pedal immediately, and then get back in gradually, the pass is ruined anyway, and means nothing. Dont ruin the car.
Observe. Watch what the fast guys do, cause they know what they are doing. Try to do what they do. They will show you how to stage, etc.
Almost forgot: the lane on the return road side has the right-of-way to the exit. Unless you are way ahead or way behind, yield to the racer on the return road side.
