Acres and acres! There are a good dozen trails out there. The one where the two Jeeps were having so much trouble is called "Initiator." It used to be a warm-up. You could get up it with minor mods. Now, it's a bit more demanding. Even still, some technique goes a long way. The Rock Wall has rejected me the last two times I went, but not this time. I walked right up it, but I also had a great spotter.
Anyway, some of the trails are seriously challenging. There's a short spot called the Rock Garden. You have to be locked all around and have some serious traction to even start it. haha
