Why going? Because it shares the same geology of Valley of Fire but it's open to trafic (OHVs and MTBs), that's the (stong) appeal.
I went twice by MTB and the motorized traffic was never too intense to bother me.
There are lots of free camping opportunities, but at the main one by the trailhead expect a concert of generators (it's unfathomable to me why people camp with generators, but, eh, to each their own).
