I can understand if you think it’s not worth your time but I think it’s a great opportunity regardless of your experience level. Why beat on your own car when you can beat on someone else’s. It’s less than a hour from Vegas so you can make a trip down there too if that interests you. Personally I had a great time and I’m going back in August. Why don’t you see if they have a level 2 course that you could take instead. The challenge for you would be to see how fast you are given a few laps on a track you’ve never been on. The instructors know the track better than you and they’ll let you go flat out a few laps but it’s a mixed bag depending on the rest of the students experience level.
