Very remote!
I visited in July. The road is all dirt and very dusty.
Father and Sons campground is an old Boy Scouts camp. There's remnants of its past life all about the area; most interesting of all, an old baseball diamond.

I rate this a four star:
Amazingly remote and no camp fee, but if you have a vehicle that can't handle the terrain, forget about making it out here. Also, if you are not a hiker and don't have an ATV or motorbike... probably not your cup if tea.
I enjoy getting a little sweaty and dirty while I'm out backpacking, so this was a fun place for me.
