This experience was a lot of fun. I did the Champ Ridge (which was a ride-along) and my dad did the driving experience. I wish I could have gone for more laps, but the ones I did have were exciting. My dad did the drive along and we got there way too early for him, so we ended up waiting a long time, but he says it was worth it.
Also, be aware that you can do this at a variety of tracks, not just Charlotte, so be sure to check out the website to see what other track locations are offered.
