The grounds are clean and orderly and the staff that I met were friendly. Showers were good, laundry was good. Location is close to some very interesting spots.
My two bads were, first, the religious tracts all over the place. I find that sort of prosthelytizing highly offensive, and second, the absolutely crappy internet service.
If a business advertises the availability of a service (wifi) then it should actually be available. One of my consistently negative experiences with KOA's is the poor wifi access. One exception was the KOA that installed repeater antennas around the campground, which provided a strong and reliable signal.
