I don't have the flyer (which came with our most recent newsletter) in front of me, but from what I remember:
The car club days are May 21 and 22. For $25, you get the entrance ticket (a $15 value), a $5 merchandise certificate, a dash plaque, and parking. Anyone riding in your car would also need an entrance ticket, which can be paid upon arrival ($15).
From calling them, the club parking area has not been determined yet. It would be first-come-first-parked and may be limited. There was no decision on opening time yet.
Maybe someone else will know some more about this.
Yes, the Pace Car car show is also May 21 and 22. On the track, May 21 is Pole Day with more qualifying May 22.
