It's worth it !!!
Through a promotion with Nextel and my employer, I won a 10 lap Indy car experience, at the time, it was called Driving 101, but now it's Mario Andretti .
I did 10 laps at California Motor Speedway in Ontario, CA, just east of the LA area .
600 hp in an open wheel car, nothing compares to it .
I can't imagine doing these speeds in traffic !!!!

If you ever get the chance by all means do it !!!!!!
