I have to disagree with the assessment that the commercial CGs in the North are much like anywhere else. How many places anywhere else have sites with a view of a lake where you can see moose feeding 24 hours a day, where beaver swim past your site and where front office service is really conducted on the honor system?
I agree that there are a couple of CGs within a 30 minute drive of the Anchorage Information Center and the downtown area that are what are considered Commercial campgrounds. Riverfront in Fairbank, Bearpaw in Valdez and many others are laid out in a similar way but are anything but "like anywhere else".
Maybe I am more gregarious than some but half of the great things we saw were recommendations from others and seemingly a lot of other folks use CGs as a social gathering place. We tried to find a "commercial CG" every so often to recharge and refill our rig and none of them were like anyplace else. I will say that all the public campgrounds we used were every bit as good and scenic as the commercial ones.
