Kick ass man! You will love it!!!! Try to get out close enough to your instructor that you can watch his lines (don't stare, but you know what I mean) , that is the best way to get to learn the track. Have some buddies take pics!
Check out the class too, you will learn lots of stuff. The first track day I did was Team chicago racing school, and the classes were pretty kick ass, and they didn't take up a whole lot of time.
