I did the one day course at the Las Vegas speedway. It was a gas. I've also done the Richard Petty Experience which was alot of fun. Skip Barber includes a half day of class and half day of driving. It's pretty amazing that they turn you loose in a de-tuned Indy car at the end of the day. The three day course includes actual racing and certification. I would highly recommend any of the courses. I will return for the three day course soon.
