I'm planning to attend this event. If you are used to going to SpeedtrialUSA, it'll be a breath of fresh air for you. The event is relax and well organized. You don't feel like you're among a sea of cars on the track and most everyone are that I met were very nice folks. They are more than willing to share their experience with you and offer you a ride.
Although they don't provide instructors, but you can find experienced racers that are more than willing to ride with you and give you pointers. Last time, Alex V., Greg H. and Marc W. offered me rides that were eye openers.
