Why no rating for a campground

A wise camper wouldn't rate his favorite nice quiet not crowded campground in any publication.

Someone has to be the first to submit a rating, why not you?
To me, the ratings do not mean a whole lot.
My idea and your idea of something good or bad may be the same or miles apart.

Since the CG has no ratings, it may mean it is average with nothing to complain about either way.
If it's on your route, try it. Even a bad CG is (usually) better than a Walmart or highway rest stop.
If it's bad, submit a rating.

Because nobody willing to review it has stayed there. Maybe because it’s a terrible place? Maybe because it’s just not on “the beaten path?” Perhaps “the camping gods” are trying to get YOU to stay there and write that review?

Ummm...I would guess because nobody has rated it yet. Perhaps it's just not a popular campground with God Sam travel planner users who are apt to rate things.
