Thats what I did when I first started. Now that I know the trails better I have a better idea of which ones I shouldnt run but still dont know on all of them. Even with being lifted and a rear locker I still have more trouble then others because my gas tank is on the side and hangs low. That with long wheel base means I get high centered easier and have much less break over angle then others.that's one nice thing about the big beginner run on Tuesday to feel out how your rig and driving abilities line up with others so you can find trail buddies. I mostly stuck with the same group all week,
One other thing to mention, if you do miss out on trail runs there are many very easy (bumpy dirt road easy) trails you can go do that are very scenic. I did that sort of thing saturday since I was tired and got to the stoop late. Also didnt feel like beating up on my truck anymore. So I just went sight seeing by myself.
