I just read this article, that gives a real good impression of what to expect during the Richard Petty Driving Experience that I'll be doing in May (less than 101 days to go).
What is interesting is that this gives a better idea of what will happen when it comes down to the actual driving. There are only two cars out on the track, yours and the instructors, with the instructor in front. This is much better in that we won't be limited by the slowest in the group.
I can't wait. This is going to be a blast.
