I did one of these last year at Mid-Ohio. Lot of fun. Got a goodie bag and ate like pigs for two days. Two parade laps. The Z and G guys got to go out by ourselves. All the other cars did it after the races were over. We were before the races.
The people running the Corral are great.
Here's a link to pictures of all of the events that they did last year.
