Rodger,
You deserve the kudos, great job!
Silver State runs twice a year, so there will always be another chance to run it. Don't beat yourself up trying to do something there isn't time to do right. It's a fun event, but you want to be ready for it. First timers have to run the "school" in Vegas, which is just one more extra thing to have to run around and get done. Not much of a school really, just a couple of follow-the-leader sessions to see if you can drive the car at all.
If your driver has previous race experience you can probably get out of the school deal.
