No worries, there will be plenty more! The run that is being coordinated with the So Cal Xterras and Frontiers facebook group is another great one to consider - it's stock friendly, 2WD friendly and will be at a nice pace that will let you get some experience with your rig(s) out in the dirt. The route that is being taken is SCCX's adopted trail that runs from Pioneertown (just outside of Yucca Valley) to Big Bear, up the east side of the mountain. It's a very easy fire road with nothing technical about it, and will give you a better idea of what your vehicles are capable of. If you can swing the time off of work, it'll be a great experience.
