We did the one in Hollister Hills, Ca last October - I drove my Gladiator. We signed up again this year so my wife can drive her Wrangler. Last year we had a great time - everything they do is geared to the novice driver, with a completely stock vehicle. We learned that our vehicles are WAY more capable than we are!
I went to Holly Hills, for the first one. It’s definitely geared towards newbies, but they do a fair job of grouping based on capability. A lot of focus on how to use features, like hill decent, etc.
They also bring the concepts out on display, so you get a unique opportunity to really check them out up close.
At the end of the day, it’s reallly a marketing pitch for Jeep jamboree, but I think it’s well worth it, especially if you have an inexperienced passenger that you want to let drive, in a controlled environment
