Lion's back is the most famous poser-rock of all 4-wheeling. Its just this ridge on the way up to Slickrock trail in Moab off to the side of the road. Any 4x4 with a decent approach/departure angle can do it, and the surface is sticky with rubber like a drag strip from so many people doing it. Its just a straight shot to the top, and any 4x4 worth its gears can practically idle up it.
It is, however, pretty exhilerating because the drop off is so abrupt on either side. Fun, kinda; hard, not in the slightest. It did make my balls tingle a bit.
