i think haunted hills is a good one to start with.
sure its a pretty technical track, but that only really comes into play when you want to go really fast around it.
for beginners its good cos its not hard on your car, its not ultra fast (3rd gear max) and you dont have to worry about faster or slower traffic out there with you.
theres no need to impress anyone with your times, no one will care how fast or slow your going (unless you beat them )
hh was my first track day, i began with around 71sec laps, and improved to a 64 on my first day.
im now in the 61's and ill be out there on the 13th hoping my new rear swaybar makes me go faster and not slower
prepare to be hooked on racing... i know i am
