There is or was a las vegas jeep club that has a web site (they saved my butt a few times) and also another large club that has runs over by baker, my fav is dumont dunes just west of baker and the surrounding area (mines with free cabins and stuff,pop your hood and hook up the lights to your battery leave it as you found it type) a lot of cool washes power lines dunes flat stuff rocks ect, lookup the desert megaphone and try to find it! just be carefull and do not go to fast out there (air lifting is spendy if they find you) and you can head into death valley from there also (and stay out of the small dunes by the hwy in the park (don't ask)get a good map and book and go for it, it's all good.
