I always place reviews like this in context. This is not a wilderness or solitude seeking campground, it's in the middle of a 1 million plus population metro area! However, it is shaded, very clean and organized and surprisingly quiet for the location. Online reservations and expedited check-in are excellent.
Healthy grass and shade trees, and level, paved pads and drives. Clean functional restrooms, and all the amenities to make camping here easy. Great for kids and pets (appropriate, fun facilities). This is one of the higher-quality KOAs we've used on long road trips with a small camper/RV.
If you are traveling in an RV and wish to stay parked, there is public transit to city-center and amenities a couple blocks away. I assume it's within most private ride-share service areas as well.
